Enable core file dumps when an application crashes or segmentation faults

stephenw10

Hmm, are you testing this on your 2100? In 23.09.1?

JonathanLee

@stephenw10 No that version disabled my crypt chip I am still on 23.05.01 it is the only version that works for everything I need

JonathanLee

@stephenw10 squids uid is squid and we are running commands as root does that matter?

stephenw10

Nope that should be fine. This isn't a Squid specific issue, applies to any process I've tested this with. So far.

stephenw10

Hmm, maybe not. This does seem to be a permissions issue. Processes run as root will coredump as expected. Or at least try, some fail with lack of space for me.

Most services run as separate users though and cannot.

Though the main Squid process runs as root...

JonathanLee

@stephenw10 weird right it should core dump

It’s for all of them Steve wheeler said, it’s a bug.

@JonathanLee said in Enable core file dumps when an application crashes or segmentation faults:

https://redmine.pfsense.org/issues/15555#change-73638

Yeah it appeared to be only non-root processes but the main Squid process is run as root (which is bad!) and still fails to create the core dump.

JonathanLee

@stephenw10 we should still get core dumps right if it’s enabled. We found a , it’s not just squid.
