Hi all, I'm hoping someone could help me solve this problem. I've been using unraid for ~1 year.

 

Problem: I can't access the main menu via browser. EXCEPT for about ~2 seconds only AFTER a reboot (when logging in).

 

I've read through many threads and tried quite a few suggestions (most are from Joe L.), none of which have worked. Like checking/restarting emhttp, memory test, update to latest unraid version.

 

I can access unMenu (as long as I don't try to access main menu), ping server, access flash drive and (when I had the array up) access files.

 

Very much the same issue as this thread (http://lime-technology.com/forum/index.php?topic=21768.0) but the solution in that isn't an option for an established server (to my understanding).

 

I was running 5.0b14, I am now running 5.0rc11.

 

I have limited linux knowledge, but can carry out commands via telnet fine.

 

I'm unsure as to when the problem appeared as I don't access main menu very often. The only changes on my 2 computers has been installation of Windows 8. But the same problem exists with using Windows 7 too.

 

If I had to guess it feels like the requests to the server "hang" and "time-out", never loading. Some ESTABLISHED processes (seen in netstat command) seem to stay open (I should think they should close?).

 

So.. any ideas? I'm open to suggestions.

 

Thank you in advance for your time.

 

Edit: syslog added.

Thanks trurl, forgot to add it. Now uploaded.

Im still also having this issue. I posted about it yesterday but deleted my thread as a fresh install of RC11 seemed to fix it. However today, after having been using the box successfully with SAB, CP and SB, and after sitting idle for an hour or so, I've lost the GUI. I can access all other functions -telnet, SMB shares and unmenu, and also all the plugin pages, but the main web gui is gone.

 

Cannot understand why - I've checked other threads on the issue, most are solved by re-installing but after 2 weeks of trying to get a stable unraid install going I don't want to turn back from here.

 

Can anyone offer some assistance? Log is attached.

 

Cheers

I've read about 30 threads on this issue and it seems there has never been a defined resolution, nor even a common cause identified. I've seen memory issues suggested as a cause, so I thought I'd add my memory stats just in case they reveal anything??

Would be great if someone can check into this. I just cant figure it out.

I have plenty of memory free, I don't run any memory intensive scripts.

Yeah I am not sure its a memory issue tbh. Hopefully someone in the know can offer some suggestions.

Looks like after awhile I lose access to unmenu too (haven't tried since my initial post).

 

I can use following commands to get unmenu back though, unlike commands for emhttp which do nothing for main menu.

 

killall awk

/boot/unmenu/uu

 

If I try to access main menu through unmenu, I lose access to all of unmenu too and need to do the commands above to get it back.

 

Edit:

 

Using the commands below and waiting for the processes shown in netstat command to close, I am able to access main menu again.

 

killall emhttp

nohup /usr/local/sbin/emhttp &

 

Edit:

 

Highlighted in bold tomorrow i what I believe to be the problem. The telnet session is fine. The others are whats created when main menu becomes inaccessible. If I click again in main menu, another process is created like the two in bold below.

Did you ever use the unrAID flash drive with another motherboard on your LAN?  It almost sounds to me like you have a conflict of MAC addresses or IP addresses.

 

Look in your config/network.cfg file

If there is a line similar to this one, delete it and then reboot your unRAID server.

HWADDR=XX:XX:XX:XX:XX

I have never used it with another motherboard on my LAN. Infact since my trial, and subsequent purchase of a key, it has only once been disconnected and that was to tidy up wires.

 

My config/network.cfg file doesn't contain the line you suggested to delete. I've got.. (where server static IP = 10.1.1.3 and gateway = 10.1.1.1)

 

# Generated settings:

USE_DHCP="yes"

IPADDR="10.1.1.3"

NETMASK="255.255.255.0"

GATEWAY="10.1.1.1"

Ill move my instance of this issue to a new thread...good luck!

Any one? Further to what I've already said once I do log in to the main menu, aslong as I keep clicking between different menu items continously, the main menu is active. As soon as I stop, it's inaccessible till reboot or restart emhttp.

 

Edit: And if I hit F5 to refresh a few times on a particular main menu page it seems to be ok. But still means I can't do any thing as I can't hit refresh when I try to make a change...

 

Edit: Found a "kindof" working work around to automatically refresh main menu in 1 browser tab, and access it with another

Sounds like your emhttp process is being killed as your server runs out of memory.  (The kernel out-of-memory process will pick a process that is idle the longest to kill in an attempt to free memory.)  By constantly refreshing it, it is not idle the longest.  It is highly possible one of your add-ons is using up all the memory..

 

Your earlier post if the output of "free -l" seems to contradict my best guess. 

 

I still say, temporarily disable your addons by renaming the extra and plugins directories, rebooting, and seeing if the issue exists on stock unRAID.  (you can then rename them back if it does)

Are you certain there is no IP address conflict? Turn off the server and ping the address.

I've previously tried this, and when server is off there is no ping response. I have already checked the MAC address of the server and what's reported in the modem/router and they also match fine.

I'll try this when I get home tonight and report back. Only considerable add ons I can remember installing was php and unmenu. And a couple scripts like the shutdown option and something for smart history.

 

Would seem bizzare for a stable system of 1 year and with an uptime of over 220 days (last taken down to upgrade to lower watt cpu) to suddenly start doing this nonsense.

Disable SMART history. It caused issues in another thread.

I don't have any "extra" and "plugins" directories. From what I can tell it's all gone into "packages". I renamed that folder, turned server off and on again, but the problem still exists.

Have you tried to reboot your router?  (again, just a guess....  The only other thing I can think of is something on your LAN is preventing access.)

Yes, this was the first thing I did when the problem occured. I'm mystified. Apart from the main menu, everything works perfectly fine.

 

I will try a new router I've got laying around when I have the time, just to eliminate that as the potential problem.

 

Is there any way to do a fresh install of unraid and keep the files containing information on the current array/parity setup?

I am having the EXACT same issue.  CP, SB, Sab, Unmenu all continue to work fine only web gui fails.  Do you have simplefeatures installed as well?  I can shut down the array from unmenu and restart and it will work for hours to a day or 2 but will then fail.  It does feel like a hung http session causing the issues.  But i get segfaults when trying to start it again.  I am going to start yet another thread for my issue and will continue to watch this one. I love the potential of unRAID but my wife feels like an unRAID widow as I spend so much time trying to get it to work how i want it to.

I seem to have the same problem since RC8a - first v5.0 version I installed after v4.7.

Sounds like we've got an undetected bug in the unraid software. I wouldn't be surprised if more and more people start to experience this issue.

 

I first experienced it with 5.0b14. Only common denominator thus far is version 5.

 

My server is connected to a UPS so no power outage is responsible (and haven't had one any way).

 

Do you have simplefeatures installed as well?

 

Rings a bell. I remember installing that when I trialed unraid, but I didn't like it and would've deleted it.

Just to be clear, you are saying this occurs with a completely vanilla install, no add on packages at all?

If you read the thread you would know the answer I think.

 

I disabled the "packages" folder, and rebooted, but the problem remained. That's as vanilla install as I've tested.

 

Am I able to backup my flash drive, and put a fresh unraid install on it without affecting existing hdd array + parity drives? I suppose if I disconnect all drives unraid can't touch them eh?

 

I'm still inclear on whether I can do a fresh install and move over various unraid files that contain the array + parity information. Like you would do in Windows if you reinstalled the OS and copied over some setting files....

Haven't tried to access menus in 24hours, and seems I have managed to get 8080 port to hang too.
