The Check_MK Microcore may need a long time for completing stop/restart of the process waiting for currently running operations to finish.
One possible situation was that the Check_MK check helpers currently execute checks in form of SNMP queries. A common case is that the helpers wait for the response of a SNMP device which may take up to minutes, depending on the "SNMP timing settings".
We have now changed the logic that these SNMP queries are terminated which leads to an immediately ending Check_MK check helper and also a faster ending Microcore process.
This change is especially important for cluster setups that have a tight timeout configured for the stop operation of the OMD sites. With this change the failover situations should be handled a lot faster and more stable.
