web interface falls over!

Featured Replies

unraid 6.01

 

My server runs quite well but every time after about 1/2 hour the web interface totally falls over. the shares and everything else continues to work and i can get to it using telnet or the unmenu plugin interface.

This is the same as it was with v5.x and v6beta6 and i had hoped that it would be fixed with v6.01.

 

I can reproduce it every time i boot the server

 

I am using a HP ProLiant MicroServer.

Your syslog indicates unRAID is clearing disk3 and your server will be offline until it completes.

 

Why are you not using the preclear script?

 

  • Author

yes it is clearing the disk but that is unrelated to the issue at hand.

 

what is the preclear script?

See search tips in my sig.

 

Preclear script allows you to clear the disk before giving it to unRAID so unRAID doesn't have to clear it, thus your array doesn't spend a lot of time offline. It also does a very thorough test of the entire disk. Making sure your disk is trustworthy is very important in unRAID since each disk is needed when a disk must be rebuilt.

 

Go to Tools - Diagnostics and post the results.

"falls over" means what exactly?  (Assuming clicking a link just causes a hang).  Please obtain syslog after server is in this state.  Also have you tried 'safe mode' (boot option) in order to discount plugin causing this?

That syslog was after it had fallen over.

 

When i say falls over it just acts like there is no web server at all. When i get to work i will re boot the server and get another syslog for you again.

it looks like the web server daemon just dies.

Yes it is crashing:

 

Jul 17 09:20:36 micro kernel: emhttp[1590]: segfault at 0 ip 00002b1c9c512426 sp 00007fff2c0aedf8 error 4 in libc-2.17.so[2b1c9c48b000+1bf000]

 

But:

 

Also have you tried 'safe mode' (boot option) in order to discount plugin causing this?

 

 

  • Author

I have just booted into safe mode now to see what happens, i will let you know.

 

BUT

when i first booted the server with a clean install before i even got to register the server with a key it crashed.

so to set it up i had to keep rebooting it, each time getting it a little more setup.

when i first booted the server with a clean install before i even got to register the server with a key it crashed.

so to set it up i had to keep rebooting it, each time getting it a little more setup.

This is the same as it was with v5.x and v6beta6
So you set up a fresh key no addons with 5.x, had the issue, set up a fresh key no addons with 6b6, same issue, fresh key with 6.01, same issue?

 

Since it seems your situation is relatively unique, I'd  be inclined to think that perhaps you have a marginal stick of memory, or some other hardware fault, assuming that a totally stock install has issues on your rig.

 

Have you run memtest for at least 24 hours to see if it spots any issues?

I initially thought that the ram was the issue too when 5.x and 6b6 did it but after swapping out the original 2gb stick for 2 4gb sticks the issue was still there.

 

Yes totaly stock unmodified thus I found out about unmenu and installed that so i could clean shutdown the array.

 

I can now report that with the server booted up in safe mode the issue persists.

I also have a unraid server running at home and it works like a charm but different hardware.

 

You say you changed memory but you never answered the question of whether or not you had actually done memtest.

sorry, yes i have. it ran with no errors.

So, I have a second server the exact same minus the ram upgrade. I have been using it as a test ubuntu server for a while.

 

I installed to a new flash drive a freshly unziped copy of 6.01 made bootable and chucked a drive in it.

 

As i was just trying to register a trial key to test the different set of hardware, BOOM, same issue.

 

Here is the syslog.

You have something on the network that appears mis-configured, but I'm not an expert.  The same 4 lines above appear in every case you have shown.  The "sshd: Bad protocol..." message appears first, then within a second the 2 telnet messages, then in about 5 seconds the segfault occurs.  The timing is too precise to be coincidental, so the bad info from 192.168.0.2 clearly seems to be responsible for the segfault.  It happened to both computers.

 

The network device at 192.168.0.2 is unusual, perhaps wrongly configured?  On the first server, the gateway is set to be 192.168.0.1, a DHCP lease is requested, and it gets it from 192.168.0.2 for 192.168.0.33, so apparently a DHCP server is running on 192.168.0.2, not on the gateway.  The second server (with a unique and different MAC) sets the gateway too, and requests a DHCP lease.  Again, 192.168.0.2 offers it 192.168.0.33, even though that's in use!  It tests and declines it a couple of times, then gets offered 192.168.0.45, and after testing it accepts it.  Seems to be a very strange and defective DHCP server on 192.168.0.2!

 

Then 192.168.0.2 keeps sending these bad protocol packets, seems rather suspicious.  Each time, a different but similar port is used.  I'd like some of our true networking experts to take a look at these messages.

 

What can you tell us about 192.168.0.2?  And is it necessary?  Couldn't 192.168.0.1 provide DHCP services?  You could stop the DHCP confusion by setting static IPs on both servers, but that won't stop the bad stuff that 192.168.0.2 is spewing.

interesting i hadn't considered something else on the network knocking it over.

yes i do need 192.168.0.2 , it is the a rental server from one of our software vendors.

 

It was installed before i started and i don't have any access to the server as they don't want us running anything on there server.

It is running some sort of windows server edition and runs the domain and DHCP.

Sounds like the server is partially abandoned and may be hacked. In any case, having two DHCP servers active on the network is causing issues, so if you can't mess with .0.2, then at least turn off the DHCP on .0.1

 

As a test, could you temporarily plug in a plain home router as a poor man's firewall? Put the network cable from your internal network into the WAN port of the router, and plug the unraid server into the LAN side, along with a PC to test and manage the unraid box. That way you could isolate the unraid server but still give it internet.

If nothing else, you need answers from someone about that rental server!

* Who's maintaining it, and is it secure?  Are they sure it hasn't been hacked?  It's on your internal network, with access to everything!

* Why is it providing DHCP services, instead of the gateway machine?

* Why is it providing the same local IP to 2 different machines?

* Why is it telnet'ing into your server?

* What else is it doing on your server?

* Especially, what is it doing about 5 seconds after the telnet connection, that causes emhttp to crash?

*It is maintained by our software main software vendor fred.com.au and yes it has full access unfortunatly

*Im not realy sure it was setup before i started

* I dont know

* no clue

* probably all sorts

I'm sorry I wasn't clear, that I was proposing the kind of questions I would want answers to.  They were a sample of questions you might want to ask them.

+1 whatever is going on would have me pretty concerned. Someone or some script trying to telnet into a computer that was just recently setup is pretty strange behavior.

So after a frustrating conversating on the phone with the fred.com.au tech support, I have been told that they dont support Linux based systems.

 

When i asked why the DHCP server was on there server they said that they recomend because some crap about there programme knows where all the computers are or something but gave no actual details.

 

So i asked why it is sending the ssh and telnet requests and he basically just fobbed me off refusing to place fault with there server saying that the requests must be forewarded through there server because it is the DHCP and DNS server.

 

I have checked the router at 0.1 is just set as a DHCP relay sending everything to 0.2

 

I will take the test server home tonight and run it there to check that it wont fall over in my home network environment.
