|Title||Background jobs: Fixed possible "pid" KeyError exception|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
When background jobs terminated during initialization, the status information of the job was missing necessary information which led to exceptions in the status overview of the jobs and the job cleanup code.
In case you experienced such an issue in previous versions, you could remove the state files from var/check_mk/background_jobs/[job]/jobstatus.mk to temporarily fix the problem.
