Problem

You receive timeout errors from the Apache after 110 seconds in several places in Checkmk.
Additionally, you are experiencing fluctuating overall memory consumption and observe high memory consumption by Apache processes.
One more symptom can be, that the 'Background Jobs' page does not load at all with the above-mentioned timeout.

Reason

This can be due to files and folders in the ~/var/check_mk/background_jobs/ directory, which extend a certain amount and size. Typically, there should be 10 to 15 files and folders. If you exceed that amount, something might be off.

Solution


You may want to use a panel to highlight important steps.
  1. Log into the affected site omd su site 
  2. Stop the site omd stop 
  3. Make sure the site is completely stopped
  4. Remove the contents of ~/var/check_mk/background_jobs/: rm -rf ~/var/check_mk/background_jobs/
  5. Start the site omd start 
  6. Observe the memory consumption and verify there are no more timeouts
