Hi,My both CentOS 5 servers have logging problems. Logs such as messages, boot.log, kernel, spooler, and tallylog in /var/log directory are all 0 size.The kernel is: Linux 2.6.18-92.1.22.el5 #1 SMP.Since the /var/log/messages contained no information it would be impossible to troubleshoot the problem.I am very sure both systems have not been hacked by others.

I've had something similar happen a couple of times after an update. In my case the /etc/services file got it's security context clobbered when some package tried to update it's contents. When logrotate ran, the syslog daemon couldn't open /etc/services because of the error and I ended up with a bunch of empty log files.
The quickest way to check for this is the command:
restorecon -v /etc/services
If nothing prints out in response, that's not the problem. If it DOES,
that might explain it. I have been checking the contexts occasionally
to try and trap exactly when it happens. I use:
restorecon -R -n -v /etc
which walks through the entire /etc tree looking for contexts to change
but just reports any exceptions.
