After upgrading your Jive instance you receive the following error message periodically from your Search node:
The threshold for the Processor\% Processor Time\_Total performance counter has been exceeded. The values that exceeded the threshold are: 100.
You may have been receiving these alerts for the last few days after your upgrade was completed.
This behavior is normal and to be expected. After Jive upgrades, it is common to observe heightened CPU usage on the search node(s) and this is due to reindexing that occurs internally as well as when triggered manually. Depending on the volume of information that needs to be re-indexed, this process can take a couple of days and will eventually return to normal CPU usage levels after all of the re-indexing tasks are completed.
