Looks like maybe the background job status files are corrupt.

2 suggestions:

1. move the files from /omd/sites/Netradyne/var/check_mk/background_jobs/user_sync to a backup folder
2. I don’t see any confidential information, so maybe share the content of the 3 files in this folder here.

Hi,

did you move the files after the ls? i.e. mv /opt/omd/sites/Netradyne/var/check_mk/background_jobs/user_sync /opt/omd/sites/Netradyne/var/check_mk/background_jobs/user_sync_old_apr_06

Hi @gstolz

My Issues with users page is resolved after removing jobstatus.mk from /opt/omd/sites/Netradyne/var/check_mk/background_jobs/user_sync

now the page loads perfectly.
Thank you so much for your help and quick resolution of my issues.
