[syslog-ng]crash version 1.5.20 under stress with tcp

26 Sep 2002

      Hi List.
I am testing syslog-ng 1.5.20.
Its an RH 7.2 kernel 2.4.18
syslog-ng was compiled from source.
 When you flood the machine with messages over tcp, it crashes
Under udp port 514 its looks nice.
(20000 messages/min no Problem)

see Backtrace and configfile below.
Looks like the template makes problems.

best regards
Johannes
