Sabnzbd closing without any errors in the logs

[randyklein]

For the past few months, Sabnzbd has been randomly closing without anything in the logs. I'm running the latest version on ubuntu. I've tried updating to the latest (a few times), and totally uninstalling, deleting all of the config files, and installing. It seems to happen when its working on larger (5 gig?) files. When I check the log after a close, there isnt anything at all there. I'm not sure what to try next to troubleshoot. Anyone have any good ideas? Thanks for the help.

Run SABnzbd from a console (so: sabnzbdplus), and wait until it stops. Then check what's in the console screen.

When I try to run it from console (sabnzbdplus) I get the following:

Code: Select all

media@mediaserver:~$ sabnzbdplus

    rc = f.close()

Thoughts?

What is the output of "free -m"?

[randyklein]

Wow, you are good. Looks like you might have just solved it... It looks pretty low. I'll work on reducing the memory. Here is the output:

Code: Select all

media@mediaserver:~$ free -m

Wow, you are good. Looks like you might have just solved it... It looks pretty low. I'll work on reducing the memory. Here is the output:

Yeah, I am. ;-) But not in this case: You have 2GB RAM (which is good), and you have swap (which is good too, and it is not much used), so that is NOT the cause of your error. I was just checking you were not running SABnzbd on a low-RAM system.
And read http://www.linuxatemyram.com/ to see that Linux will eat all the RAM it can. So no problem there.

Can you run this:

Code: Select all

python

import platform
platform.system()

and post the output here?

[randyklein]

ok, that makes sense. Webmin is showing that I have plenty of free memory. Below are the results. Thanks for all the help!

[sander]

OK, that's the cause of your problem: a problem with your system or python setup. See below for the expected behaviour.

So: not a SABnzbd problem. You could type 'uname -a' on the command prompt to further investigate it.

So:

Code: Select all

uname
uname -a
uname -p
uname -s

Code: Select all

sander@R540:~$ python
Python 2.7.3 (default, Sep 26 2012, 21:51:14) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform
>>> platform.system()
'Linux'
>>> 
sander@R540:~$

[randyklein]

Ok, I got "sabnzbdplus" to work at the terminal by just commenting out that line in the _init_.py file. Its fine since i'm using linux not win.

So, now back to my original issue. When I run "sabnzbdplus" at the command prompt it runs, then completes the command. I dont see any logging info / running info. Here is what the output looks like:

Code: Select all

media@mediaserver:~$ sabnzbdplus                                                
media@mediaserver:~$    

Am I doing something wrong?

[sander]

Why don't you solve the system problem? That's the root cause. I don't know which line you commented out, and what the effect is.

If you run "sabnzbdplus" and it's already running (and it is set to start a webbrowser), it would say:

Code: Select all

sander@R540:~$ sabnzbdplus 
sander@R540:~$ Created new window in existing browser session.

sander@R540:~$ 

You don't get that message, so that makes me a bit suspicious (but maybe browser-auto-start is set to off?). Anyway: check if sabnzbd is running:

Code: Select all

sander@R540:~$ ps -ef | grep -i sabnzbd
sander   11387  5138  4 17:59 pts/2    00:00:09 /usr/bin/python -OO /usr/bin/sabnzbdplus
sander   11686  6727  0 18:03 pts/3    00:00:00 grep --color=auto -i sabnzbd
sander@R540:~$

HTH

[randyklein]

well, i'm running it in a non-gui environment, so I dont think it can open a browser. Even so, in your screen shot it is completing the process once it opens, so you still wouldn't see any log if the process errored out. Right? Am I missing something?

After I type "sabnzbd" at terminal I am able to connect and use it.

[randyklein]

also, below is the code I commented out. It's all in the one clause. Apparently, Darwin = Mac. I'm running on linux, so I should be safe.

Code: Select all

#    if platform.system().lower() == 'darwin':
#        DARWIN = True
#        try:
#            import Foundation
#            FOUNDATION = True
#        except:
#            pass
#        if platform.machine() == 'i386':
#            DARWIN_INTEL = True

[sander]

Apparantly you're already running SABnzbd as 1) you can access it and 2) running sabnzbdplus does not show anything. Did you start it as a daemon? If so, you indeed can't see stderr / stdout logging.

FWIW: in __init__.py there's another platform.-call: platform.mac_ver()

I still find it a pity that you don't solve the root cause, and that you don't show the output of the uname commands ... This way your problem comes back at the moment you use another SABnzbd version ...

[randyklein]

Sorry, I didn't address all of your original questions / points. Honestly, I dont know if I'm good enough to fix the underlying issue. The init.py was executing fine, so I figured I fixed the issue. But you're right about the upgrade.

It looks like you were right on the running part. I have it started now, i'm going to try to get it to error and report back.

Here is the result of uname -a:

Code: Select all

media@mediaserver:~$ uname -a                                                   
Linux mediaserver 3.0.0-17-generic #30-Ubuntu SMP Thu Mar 8 17:34:21 UTC 2012 i6

media@mediaserver:~$    

Thanks again for the help! I really appreciate it.

[randyklein]

so a quick update. That helped find the issue. It was a "segmentation error" which apparently is something outside of SABnzbd. I'm just going to go ahead and rebuild the machine to clean everything up. Thanks for the help Sander!
