I keep seeing CPU spikes on production web servers running v9.3 and 9.3 that has an impact on the end users. They come in roughly 45 minute bursts and running procmon indicates the cyserver.exe is causing them. One suggestion ive had is to clear the content cache in the possibility that a bad update is trying to correct itself. Beofre I try that I want to find out how to lower the logging level for an agent policy. Has anyone tried that and if so what did you do?</P> Thu, 03 Sep 2026 10:23:21 GMT S.Howard118149 2026-09-03T10:23:21Z https://live.paloaltonetworks.com/t5/cortex-xdr-discussions/xdr-cpu-spikes-and-logging-levels/m-p/1263578#M9543 <P>Hi</P> <P>&nbsp;</P> <P>Has anyone else come across this?
