TarMK compaction thread is not getting stopped at the scheduled windowEndTime

Question

We are using the default daily maintenance window 2.00 to 5.00 configured at /libs/granite/operations/config/maintenance/granite:daily

TarMK compaction thread is getting started at the scheduled start time of 2.00 AM, but it is not getting stopped at 5.00 and it is running till it gets completed( The complete run takes around 7 to 12 hours).

Also if we try to stop the server at that time (when TarMK compaction is running), the stop process is waiting for the TarMK compaction to get completed. we need to kill that process to get it stopped, otherwise we need to wait for the TarMK compaction to get complete.

kindly help me on this.

I checked with Support on this issue - this was the response:

This is one of the possible issues one can run into with “Online Compaction” which is not recommended for AEM 6.0 & 6.1.

For AEM 6.2 (though not likely the case for this customer), we have restricted support for online compaction (subject to evaluation on case by case basis by support & engineering team).

Online Compaction is turned off by default on AEM 6.1 & 6.2. Offline Compaction as documented at [1] is the recommended approach:
