June 5, 201511 yr This is an interesting thread but I can see it esculating out of control which would be a shame because anything that helps improve stability is a good thing. I don't believe any of the replies you have had have been dismissing your concerns, they have just been trying to get extra information out of you and trying to help you track down where the source of the issue stems from, once they have that information they can investigate further with something solid to work from. I'm guessing english may not be your first language, and while it is pretty good, it can make you sound more confrontational than you probably mean to be, which is likely to annoy those trying to help you and they respond in a similar way, which you take exception to and it all esculates out of control very quickly. Please try all of the things suggested and requested and I'm sure some progress can be made on this.
June 5, 201511 yr Author Looking at his posting history, he may be running unRAID in a VM. No way. That was only an early testing environment. I'm on bare metal now, on an Asus A88XM-Plus. Please, please, pay attention to what I post before replying here...
June 5, 201511 yr Author BUT... there is this issue. Browsing from LAN (gigabit as already said...), Dynamix WebGUI on RC3 & 4 - the only I've tested - often becomes unresponsive during page load, mainly between the first two tabs (but it could be a coincidence...), emhttp CPU usage go to 100% (from Top command) and only sometimes I'm able to kill it and restart without a 'segmentation fault' error. With first two tabs you mean "Dashboard" and "Main" ? Yes! More... I've just saw that both the pages are created in two ( or more...) updates: first is displayed the main structure with tables and labels, after they are filled with values and icons... it seems to me that it's during this second phase that emhttp hangs... Interesting is the 100% CPU usage... Something hangs inside. Is it waiting for... what? When this happens can you list all running processes: ps -ef And communication state: lsof -Pni Next time it will happens I'll surely do. Now I'm trying to see If I am able to make it hangs by remote. Up to now... no hang s at all.
June 5, 201511 yr Author This is an interesting thread but I can see it esculating out of control which would be a shame because anything that helps improve stability is a good thing. I'm with you bro' I don't believe any of the replies you have had have been dismissing your concerns, they have just been trying to get extra information out of you and trying to help you track down where the source of the issue stems from, once they have that information they can investigate further with something solid to work from. I've had a different impression on some of the replies. I'm not convinced at all that Realtek NIC is the culprit, but I'll test anyway other NICs. I've not seen this open mental approach in some of the replies... I'm guessing english may not be your first language, and while it is pretty good, it can make you sound more confrontational than you probably mean to be, which is likely to annoy those trying to help you and they respond in a similar way, which you take exception to and it all esculates out of control very quickly. Please try all of the things suggested and requested and I'm sure some progress can be made on this. You are right. I'm Italian and my English is not so good. More, when I write here, often I'm on rush and/or doing a lot of other things, so it is even worse than what I could do after a proof-reading. I'm sorry for this. I write down surely better in Italian, but I think this couldn't be the same for most of you... not asking anyway. Next week I'll test more NIC. Today I'll continue to try to make it to hang from remote and after, I'll make it hang on local and I'll test the above commands and I'll report results. Attached to some of my posts here there are syslogs and more. If someone would find somethin' on them... P.S.: from my dashboard NOW... Network Interface Receive pkts Transmit pkts eth0 113509487 8086321 lo 24499 24499 Network Interface eth0 Receive: Errors: 0 Drops: 0 Overruns: 0 Transmit: Errors: 0 Drops: 0 Overruns: 0 ...not the statistics of a bad working NIC IMHO...
June 5, 201511 yr I was trying to repair ad bad spot on my cache drive. BTRFS was reporting an error on my Win7 DVR VM Img. I ran Scrub 3 times, one -r, a second time with the VMs running. The third time I turned off my Linux LAMP VM, Win7 DVR VM and Plex Docker Container. While switching between tabs to check different things the Web interface went down, but the log was still updating. The Web interface never came back and I am currently unable to telnet in to the box. The Log file still loads new data and I can access all shares.

June 5, 201511 yr Author Why are you unable to telnet? What's your NIC brand? Were you browsing from LAN or remote? Fast Ethernet or Gigabit? From wireless or wired client?
June 5, 201511 yr Today I'll continue to try to make it to hang from remote and after, I'll make it hang on local and I'll test the above commands and I'll report results. I'm confused by what you mean by remote. Could you describe what you are doing?
June 5, 201511 yr I am not trying to join the band wagon but I have few locks of rc3 and rc4. In rc3 they appeared to be related to Dockers. However in rc4 I have had web lock ups in the last 24 hours when switching from page to page quickly.

I'm confused by what you mean by remote. Could you describe what you are doing? By remote: accessing web interface NOT by local LAN clients but from a different LAN connected by VPN (slower connection since it have to pass through internet). I am not trying to join the band wagon but I have few locks of rc3 and rc4. In rc3 they appeared to be related to Dockers. However in rc4 I have had web lock ups in the last 24 hours when switching from page to page quickly. I love U bro'... What NIC brand are you using in both unRAID and client machine? Both on gigabit? One of them on wireless LAN?
June 5, 201511 yr Author When this happens can you list all running processes: ps -ef And communication state: lsof -Pni I've to admit that is very "hard" to make WebGUI to hang by remote BUT... at the end I've succeded in it! (at the contrary, locally, on my system, it hangs very frequently...) After a LOT of fast changing pages on interface, at the end it hanged on loading "Dashboard" page which remained partially loaded, with only Tables & labels loaded and no info/icons in it. I've attached all you have requested and a top and a Syslog too (taken from unMENU, that, as usually, was ever working...). After that I was able to reboot server with a reboot command from CLI with no issue. I've to say that, this level of "usability" is not so bad for me: it doesn't hang if not rarely by remote and I mainly will access it this way, so, for me, it could be even good... Two things to note in my opinion: 1) Top reports even a high memory usage. It's very strange since server was doing nothing else that following me on browsing WebGUI and I see ever very low memory usage from WebGUI Dashboard (about 15/25% of 4 GB) 2) Only few lines of syslog are related to today. I connected by telnet after WebGUI hanged, and previous lines were only: Jun 5 16:07:56 unRAID1 emhttp: /usr/bin/tail -n 42 -f /var/log/syslog 2>&1 Jun 5 16:10:09 unRAID1 emhttp: sendOutput: write Jun 5 16:10:09 unRAID1 emhttp: sendOutput: write Syslog had been showed correctly to me. Then, when I changed page again, after some changes... BANG. No error in syslog anyway related to this...

One of them on wireless LAN? Unraid is Supermicro - X9SCL/X9SCM Baremetal remote machines are both a Mac and a ESXI win 7 VM... All GIG all the way
June 5, 201511 yr Author This is my top during normal working of WebGUI. Note how occupated memory is very lower than when emhttp hangs. I don't know if it is emhttp taking all that memory when it goes to 100% CPU usage anyway... I saw a very high "cached memory" with WebGUI hanged. Could it be related? There was no data transfer at all... disk were all spinned down...
June 5, 201511 yr I spotted a possible deadlock condition and there's a fix for this next release, might solve this.

June 5, 201511 yr Why are you unable to telnet? What's your NIC brand? Were you browsing from LAN or remote? Fast Ethernet or Gigabit? From wireless or wired client? unRaid fails to respond to telnet requests after the web interface goes down. Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06) Gigabit to Gigabit over Gigabit Switch I have also seen the Docker / KVM Network issue, but given that I could still access SMB shares, this was not that.
June 5, 201511 yr Image In this picture the background process monitor issues a "wget" to get the latest emhttp status and it appears to hang. Maybe the condition that Tom is referring to, is related to the simultaneous background access (monitor) and foreground access (GUI) of emhttp ?
June 6, 201511 yr Author unRaid fails to respond to telnet requests after the web interface goes down. Never seen this behaviour in my tests. Only one time I've been slammed out of my server but because of a bug of unMENU... In this picture the background process monitor issues a "wget" to get the latest emhttp status and it appears to hang. Maybe the condition that Tom is referring to, is related to the simultaneous background access (monitor) and foreground access (GUI) of emhttp ? Very interesting. I hadn't noted it... If I have well understood this could be 'compatible' with what I reported: it hangs between the 'first & second' part of page creation (tables+labels & values+icons). First ones are static, about ever the same, seconds need real time data to be filled in... Am I wrong?

June 6, 201511 yr Had an occasional hanging of the UI in RC3, however on RC4 it is frequent (daily). Telnet and shares are still accessible, on issuing 'powerdown -r' the pc reboots but after loading the PCI cards it reports 'machine check error' prior to loading unRAID. After manually powering off and on, everything loads up. Will post a diagnostics file when it happens again.

I would also like to see the output of these commands when your system hangs: ps -ef lsof -Pni
June 6, 201511 yr Will do bonienl Took a log of these today during normal operation for comparison also.
