we recently upgraded to PI Server /Analytics/etc to the latest - 2018 SP3. we are now experiencing very high cpu times on the Primary PI Archive server - when its pegged at 100% the system is unusable - unable to connect - completely locked up. we direct other users to the secondary server - but this is only a work around. 


this behavior was not happening before the upgrade.
