Public bug reported:
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:

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.
