Do I need to install the log4j cop file again after a SU update of CUCM? I installed log4j fix weeks before the update. It was 11.5 SU9 before and CUCM was updated to 11.5 SU10. I know the cop file removes the log4j jar files but I don't know if SU10 installs it again. I also don't see the log4j cop file via show version active command.

If SU10 is also affected by the log4j leak (don't have it in mind, but I think it is), then yes, you have to install the cop file again.

Yes you'll need to install the fix for the defect again if you have performed an update later to a version that is affected by the defect.
