Hi list, I've used Nagios for a few years now, largely without any problems, but since I just rebuilt my Nagios server I'm having a problem.
My nagios log file is full of entries like this, that recur every few seconds: Error: Unable to rename file '/var/log/nagios/spool/checkresults/checkf8zhrH' to '/var/log/nagios/spool/checkresults/c8M6TqA': No such file or directory Warning: Unable to move file '/var/log/nagios/spool/checkresults/checkf8zhrH' to check results queue.

Error: Unable to rename file '/var/log/nagios/spool/checkresults/checkyHICiz' to '/var/log/nagios/spool/checkresults/c28Thaw': No such file or directory Warning: Unable to move file '/var/log/nagios/spool/checkresults/checkyHICiz' to check results queue. Error: Unable to rename file '/var/log/nagios/spool/checkresults/checknXxstZ' to '/var/log/nagios/spool/checkresults/cNhpsRH': No such file or directory Warning: Unable to move file '/var/log/nagios/spool/checkresults/checknXxstZ' to check results queue. I see from searching for the problem online that it can be caused by multiple running instances of nagios. When I do a "ps -ef | grep nagios" there are usually 4 processes - one that seems persistent (2337 in this case) and the other 3 that disappear and reappear with new pids. Killing the 3 "extra" processes makes them just reappear. Is this normal? [root@monitor ~]# ps -ef | grep \/usr\/sbin\/nagios nagios 2337 1 0 13:05 ? 00:00:02 /usr/sbin/nagios -d /etc/nagios/nagios.cfg nagios 15453 1 0 13:12 ? 00:00:00 /usr/sbin/nagios -d /etc/nagios/nagios.cfg nagios 15621 1 0 13:12 ? 00:00:00 /usr/sbin/nagios -d /etc/nagios/nagios.cfg nagios 15707 1 0 13:12 ? 00:00:00 /usr/sbin/nagios -d /etc/nagios/nagios.cfg root 15744 6284 0 13:12 pts/0 00:00:00 grep /usr/sbin/nagios This is a 64-bit CentOS 6.0 virtual machine. It was running SELinux but I disabled it for debugging in case it was causing problems. Permissions on ls -la /var/log/nagios/spool/checkresults/ and parents are traversable and writable by the nagios user. I also saw online that sometimes permissions on /dev/null can cause this problem, but in my case /dev/null is world-writable so I can't see a problem. I adjusted max_check_result_file_age to 0 in case my checkresult files were being deleted prematurely, but the problem persists. So, I have no idea what to look at next while troubleshooting this. Can anyone suggest a pointer?
