Sabnzbd crashes but no errors [Ubuntu]

Post by PeteWilliams »

Hi,

I am running Sabnzbd 3.2.1 on Ubuntu 20.04.2.

Recently, Sabnzbd has started crashing occasionally - I can't access the web interface and the logs imply there is no activity.

However, I cannot find any errors that explain why this might be.

If I run sudo service sabnzbdplus status it seems to tell me everything is fine:

Code: Select all

May 04 20:00:40 server systemd[1]: Starting LSB: SABnzbd+ binary newsgrabber…
May 04 20:00:40 server sabnzbdplus[289345]:  * Starting SABnzbd+ binary newsgrabber
May 04 20:00:41 server sabnzbdplus[289345]:    …done.
May 04 20:00:41 server systemd[1]: Started LSB: SABnzbd+ binary newsgrabber.
If I tail my log, I can't see any problems there either:

Code: Select all

Any suggestions as to what is happening, or where else I can find any errors?

Thanks

Switch logging to +Debug in the status and interface settings window.
Then let's check again at the end of the log before it stops.

"crash" is a big, ambiguous word. So check if sabnzbd is still running:

Code: Select all

sudo ps -ef | grep -i sabnzbd

For example:

Code: Select all

$ sudo ps -ef | grep -i sabnzbd
sander   23537     1  0 13:12 ?        00:00:00 /usr/bin/python3 -OO /usr/bin/sabnzbdplus --daemon --pidfile /var/run/sabnzbdplus/pid --server 0.0.0.0
sander   24718 24691  0 13:13 pts/2    00:00:00 grep --color=auto -i sabnzbd

So the saving to postproc file is the last thing in the log?
Then I would try to run SABnzbd in the terminal, so you see the output in the screen. Hopefully it shows why it crashes.
Or worth clearing the whole ".sabnzbd" directory.

With the script below you can verify your postproc2.sab is valid at all

Code: Select all

[email protected]:~/.sabnzbd/admin$ python3 pickle_pretty_print.py postproc2.sab 
(2, [])

with this script:

Code: Select all

import pickle
import pprint
import sys

try:
    myfile = sys.argv[1]
except:
    sys.exit("Specify pickle file as parameter")


with open(myfile, "rb") as handle:
    try:
        b = pickle.load(handle)
        pprint.pprint(b)
    except:
        print(myfile, "not a pickle file?")
        sys.exit(-1)

It was on that instance, but the next time it crashed it was something else. I don't recall but it looked quite innocuous.

OK, so postproc2.sab looks normal.

Please tell what.

As this looks like real crashes:
what is in /var/log/apport.log ?

What kind of system is it? What kind of hardware exactly?

Ah, that's a real crash. That's bad.

Did you google the 3rd line of your logging?
Did you look at the 5th, last line of your logging

Did you uninstall and reinstall SABnzbd?

Did you run memtest86+ on your HP Microserver Gen 8?

Keeping an eye on /var/log/kern.log might be easier / more useful than on apport logging.

I don't think it's crashed this week, so no updates.

I found nothing from Googling the errors.
The /var/crash directory was empty by the time I looked.
I have updated by version of SABnzbd, which I imagine is the same as uninstalling/reinstalling?

I've not done a memtest86 yet, but will do.

I've not changed anything since my last update, but it hasn't happened since, so… on hiatus?
