I believe the contact list only comes into play after an alert is triggered so I cannot think of why this change would cause the problem you describe (If I am wrong please someone correct me, I am here to learn) were there any patrches that went on you machines around the same time?

After a simple change to update the contact list, all check_nt checks are periodically failing with socket timeouts. I have upgraded to Nagios 2.8 and I have tried increasing the timeout to 59 seconds, but the problem is getting worse. It seems like every second or third check cycle all the check_nt checks timeout. Then later they will all recover. We are running Centos 2.8 on Centos 4.3. Thanks, Matthew<tt>------------------------------------------------------------------------- Take Surveys. Earn Cash.
