[syslog-ng] Problem with Syslog-ng.

Currently I am running Syslog-ng on just 2 machines, and they swap log files back and forth for security. Problem is, on one machine syslog-ng just stops running, exits silently.. Anyone else seen this? Syslog-ng v 1.3.8 Libol v 1.3.9 Linux 2.2.13 Slackware 7.0mod -Ben
