I just fought this issue. If you are running klogd and have syslog-ng configured to likewise log kernel messages (ie.: source kernel_file { file("/proc/kmsg"); };) its most likely hanging upon a read of /proc/kmesg file descriptor. Search the archives a week or two ago, and look for my posts. I document in gory detail what I saw. If you see the same thing, well, then you'll hopefully be able to resolve the issue quickly.

I apologize for the lack of technical detail in this post, but, for the moment I'm just trying to ascertain if I or my syslog-ng config are on drugs.
Basically, I have a mixed array of Linux (RedHat 6.2 & 7) and FreeBSD (4.2-S) machines on which I'm running syslog-ng and logging to a central host. (FreeBSD 4.2-S)
The problem is that the Linux boxes periodically stop logging. If I send the daemon a HUP, it comes back to life and data starts flowing again, but any log messages that would have appeared while the daemon was hosed are gone.
Has anyone experienced anything like this before?
Thanks in advance, -Snow
