Motion crashes unexpectedly

[Gabriele Tozzi]

I'm running motion on an updated 24/7 server with many other processes and no suspected hardware problems.

I'm using motion to collect data from an IP camera.
I'm also using another software to connect automatically to motion's web port on localhost and check the camera is alive.
Motion runs smoothly for hours, sometimes days.

Sometimes (let's say 2-3 times a week), motion crashes. That's what I found on syslog:

    Oct 15 05:22:59 transylvania motion: [0] Thread 1 - Watchdog timeout, trying to do a graceful restart
    Oct 15 05:23:10 transylvania motion: [1] Calling vid_close() from motion_cleanup
    Oct 15 05:23:11 transylvania motion: [1] vid_close: calling netcam_cleanup
    Oct 15 05:23:11 transylvania motion: [1] netcam camera handler: finish set, exiting
    Oct 15 05:23:11 transylvania motion: [0] Motion thread 1 restart
    Oct 15 05:23:11 transylvania motion: [1] Thread 1 started
    Oct 15 05:23:11 transylvania motion: [1] Resizing pre_capture buffer to 1 items
    Oct 15 05:23:19 transylvania kernel: [5717631.158791] motion[17206]: segfault at 131 ip 00007fa135bed248 sp 00007fa12d7b4438 error 4 in libjpeg.so.8.0.2[7fa135bb9000+3f000]

Talking with the guys on #motion, they said "libjpeg errors are often due to jpeg vs jpegturbo without a rebuild"... not sure if this info is useful.

Restarting motion makes it work again with no problems until next crash.

I'm attaching my motion.conf (comments removed for readability) and .crash file. If you need more info, please don't hesitate to ask.

Thank you.

Status changed to 'Confirmed' because the bug affects multiple users.

Probably, this has been fixed, see https://github.com/Motion-Project/motion/issues?q=is%3Aissue+is%3Aclosed+segfault

This was also reported for a version from 2013~2016 and is I think no longer relevant. If that is the case, this bug can be closed.
