I am observing high CPUusage touching 100% after splunk upgraded to 9.0.2 , is this expected ? If so , please share the recommended remedy .
I'm not sure if that's the case, but version 9.0.4 solved several issues included thread and memory usage
|After upgrade one set of clustered indexers has increase in thread crashes during search
|Search utilize huge memory on only one indexer.
Hope this will help you, have a nice day,
