CQM2058E IN-COLLECTOR ELAPSED TIME LIMIT EXCEEDED FOR THREAD thread_id ssid plan_name
The monitoring agent has been detected to be consuming CPU for a time period greater than specified in the HM_TIME_LIMIT parameter in CQMPARMS.
The thread ID is the Db2 thread token for the thread consuming the CPU, the ssid is the Db2 subsystem running the thread, and plan is the plan name the thread was executing.
Review the CQMPARMS parameters, HM_DUMPS and HM_TIME_LIMIT (these parameters set the thresholds for in-collector health monitoring).
In environments with high CPU contention, the HM_TIME_LIMIT parameter value might need to be increased to avoid false positives. An SVCDUMP will be taken if the HM_DUMPS limit has not been met.
