[syslog-ng]syslog-ng dying on hup - solved

31 Oct 2000

      Hello all,

I solved the the problem and I thought I would share the solution with everyone.  The problem was that by logging using $program, occasionally a $program was blank.

Syslog-ng would then try to write the entry to the log file.  And since $program was blank, the log file was the current directory!  I simply added to the filter 'goodprograms' and all was solved.

Below is the full config file.

Cheers,
Nija
