I have Nagios Core 4.3.2 on RHEL 6.6 and few days ago i don't have any problem.
I started to add a linux host into my cfg file and after than Nagios started to run with problems.
The last check time is still 3rd of Oct. and when i reschedule the host check, it's waiting (after i clicked the Commit button) and timed out.
Everything looks ok but nothing works.
Could you please help me ?
Thanks
