Hi list,
I'm running syslog-ng 3.4.3 (installed from FreeBSD ports) on FreeBSD 9.1 with self-written patterndb file to parse apache error_log, mod_security and pagespeed errors.
The syslog-ng source is httpd error_log file, after starting syslog-ng it core dumps:
ERROR:logmsg.c:1303:log_msg_unref: assertion failed: (LOGMSG_REFCACHE_VALUE_TO_REF(old_value) >= 1)
Let me know if you need more info.
