I have a feeling this could be caused by duplicate versions of a cronjob running in parrallel

Can you run the following

Code: Select all

ps -ef |grep eventman

Not sure if we can catch it happening, but worth a try...

That is what I thought...

Can you post the following to see if we can track down why there are 2 of them running

Code: Select all

cat /etc/cron.d/nagiosxi
crontab -u nagios -l

Nice work Sherlock!

We have fixed this in the upgrade script, but to eliminate your problem I would remove the items from the nagios user crontab and keep the /etc/cron.d/nagiosxi file as this is what the system will expect.

Excellent! Minor issue but glad you found it!

Can I get a little more detail on what I need to do, which file and which lines to remove? I'm still Linux n00b (but with your help I'm getting better!)...

Thanks!

Sorry, you can run

Code: Select all

crontab -l -u nagios | grep -v /usr/local/nagiosxi/cron | crontab -u nagios -

Thanks Scott, I appreciate the hand holding and expertise!
