I’m running URBackup server in a FreeNAS jail. It’s been running very well since July '16.
I updated to 2.1.18 a couple of weeks ago.
It’s ran completely fine until this, Mar 27 19:36:45 freenas kernel: pid 25941 (urbackupsrv), uid 1001: exited on signal 6 and again Mar 28 13:29:08 freenas kernel: pid 42176 (urbackupsrv), uid 1001: exited on signal 6
Google tells me, Signal 6 is SIGABRT – see /usr/include/sys/signal.h. A process dying
with this signal is usually due to it calling the abort(3) function.
That generally indicates that the process itself has found that some essential pre-requisite for correct function is not available and voluntarily killing itself, rather than the process being killed by the kernel because it ran over resource limits or looked at memory addresses funny or something.
Any clue as to what’s going on greatly appreciated.
