Martin, were you able to solve this problem by changing check_result_reaper value? I am also receiving the following error. Thansk [1241449457] Error: Unable to rename file '/var/log/nagios/nagios.debug' to '/var/log/nagios/nagios.debug.old': No such file or directory [sr2690@xxxx]>ls -ld . drwxrwxr-x 6 nagios nagios 4096 May 4 11:07 .

The problem persists across nagios restarts and reboots. Thanks -- <div><div></div><div>Martin A.

I have a feeling that your check results are already stale before the reaper gets a chance to process them. tip: for a while, try setting max_check_result_file_age to 0 and see if you'd still get these errors. if not, then its a timing misconfiguration. cheers, Marc.I </div></div> ------------------------------------------------------------------------------ Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.
