On RH I've never got a core dump....Do you know a method for generate a
core dump file? Before all possible test, why you don't give me the your
best installation procedure? However, in the attachment I send you a BT
of FreeBSD:

gdb syslog-ng -c syslog-ng.core

it is normal that syslog-ng reports garbage collecting messages.

it is implemented in 1.5.x

the problem should be fixed anyway. please do the following:

ulimit -c unlimited (to let the program dump core)
syslog-ng (dumps core)
gdb syslog-ng -c core (reference to core file)
gdb> bt (to get a backtrace where it aborted itself)

thanks,
