[syslog-ng]Syslog Dropping Information

[Mathieu MILLET]

     Hi,

I think I got the same problem than you. The trick is that syslog-ng is
restarted  when logs are rotated by logrotate, but not klogd. klogd needs some
sort of pipe to a 'syslog' daemon. So, if you restart syslog-ng, klogd still
sends data through the pipe to nowhere.

klogd needs to be restarted AFTER syslog-ng. So, at rotation time, restart both
syslog-ng and klogd.

I hope it will help.

Sincerely, Mathieu.
