Package: syslog-ng
Version: 1.9.8.1+20060128-1
Severity: critical
For the last few weeks I've had a problem with SQLGrey aborting and mail
being rejected. The problem each time was that syslog-ng was no longer
running and SQLgrey wasn't handling the missing syslog daemon more
gracefully. Syslog-ng would segfault during logrotate's run.
Stracing the syslog-ng process while running logrotate yielded the
following:

Severity of the report set as critical since in my opinion the lack of a
logging daemon can be a security problem.
