Hi, I am using the following version of syslog-ng server on a PowerPC based system running Montavista Linux. syslog-ng --version syslog-ng 3.0.3 Revision: ssh+git://bazsi@git.balabit//var/scm/git/syslog-ng/syslog-ng-ose--mainline--3.0#master#08c9bf9d98e4e021756adc12c42605840140ba8b Compile-Date: Jul 23 2009 14:23:17 Enable-Threads: off Enable-Debug: off Enable-GProf: off Enable-Memtrace: off Enable-Sun-STREAMS: off Enable-Sun-Door: off Enable-IPv6: on Enable-Spoof-Source: off Enable-TCP-Wrapper: on Enable-SSL: on Enable-SQL: off Enable-Linux-Caps: on Enable-Pcre: on Of late, I am running into the syslog-ng crashes during the boot up of the system. At the boot up time the number of messages are significantly more. I was able to collect the stack trace. (gdb) bt #0 0x00000000 in ??

If this is a known problem, is there a patch available? Appreciate your help very much. Thanks, Subra
