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. Quoting Jim Gifford <maillist@jg555.com>:
I have noticed over the last few weeks, that it seems that I have been dropping information from the kernel log. I am not sure if it is my configuration. I have tried two different ways of accessing information from /proc/kmsg. I have tried pipe without klogd. I have tried file with klogd. It seems to happen at random times.
Here is my system information. Linux 2.4.18 Syslog-ng 1.5.17
Here is a copy of my config.
