Environment

Release : 20.2

Component : PERFORMANCE MANAGEMENT INTEGRATIONS

Cause

The kaha.bak and kahadb directories are very large in size.  

Resolution

The directory kaha.bak was probably renamed by the user during trouble-shooting process with  Broadcom support.  The system does not rename these directories and therefore kaha.bak directory can be deleted without the need to stop services.  Stopping and starting the dadaemon process also cleared down the kahadb directory to smaller size.  When restarting the DA, check the karaf.log and verify the rollup job is started.  Should see entries 2-3 hours after DA is restarted, search for rollup.
