Checking logs at the time of alerting I could not find anything obvious in journalctl output on openqaworker3.

https://nagios-devel.suse.de/pnp4nagios/zoom?host=openqaworker3.suse.de&srv=Number_of_threads&view=0&source=0&end=1595383132&start=1571142185&graph_width=500&graph_height=100 shows that over long time the number of processes / threads is already at the warning threshold of 2000 but I do not remember seeing that as a problem.

Suggestions¶

• Ask SUSE-IT (EngInfra) to disable alert or help debugging
