          could this be my issue with it not even trying?

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

            killall -11 squid

            mine shows no information on core anything...

            Try using kill -6 or kill -11 against the PID rather than all 'squid' processes.

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

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

                        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... 🤔

                                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.

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