Syslogd exited on signal 11 (core dumped)

  • Completed a fresh install of 2.2.3 recently and noticed that on occasion pfsense stops writing system logs.  If I try resetting the log files, I get a message written to the system log that states syslogd "…exited on signal 11 (core dumped)".  Rebooting fixes the problem, but it's becoming a bit of a pain.  Just curious if anyone else has come across this, and if so, have you been able to fix it?

  • Is it leaving a core file somewhere?

    find / -name '*syslog*core*'

    Resetting the log files may help. Status>System logs, Settings tab.

    Do you have anything non-default configured in logging settings?

  • I found a syslogd.core file off the root.  What program can I use to view the debug info?

    Next time it happens I'll try the reset log files again, but the last time I tried, it didn't have any impact.  I do have some non default settings: 1000 log entries displayed in GUI and unchecked log packets matched from the default block rules…

  • You can use gdb to analyze it.

    Could you get that file to me? Upload it somewhere and send me the URL privately, or if zipped it's less than 25 MB, email to cmb at pfsense dot org.
