Continuous 'Service Exited in system log

I get the following continuously in my system log. Any advice on what it is and how to stop it?

Thanks

The real problem seems to be the mds_stores process since the "Service exited due to SIGKILL | sent by mds[6]" messages stop once indexing is finished (i.e. when all mdworker_shared instances have stopped and no new ones are created).

Then mds_stores continues to run for days at 30 to 100% CPU writing 10GB/Day to disk and keeping the fans running continuously.

I've stopped the indexing using mdutil, cleared the index, rebuilt the index etc. It always ends up with mds_stores running amok

This problem appeared right after the Security Update 2020-003 on Mojave.

Currently the only way to fix this is by stopping the indexing service rendering Spotlight inoperable.

In short Security Update 2020-003 broke Spotlight
