Description
Steps to reproduce:
1. build and start 3 node cluster w or w/o MXS. Build and verification is ok (green).
2. exec to the slave node 2 using docker exec -it mcs2 bash, for me it is mcs2 everytime.
3. check process list (ps aux or mcs cluster status), all MCS processes should exist
4. wait 1-2 minutes and do nothing with a cluster
5. check process list again, now PrimProc process is gone
After PrimProc gone I got those additional info:

Using MariaDB-columnstore-engine-debuginfo package I got those:

At the same time I could observe this messages at debug.log
Seems that this is not related but anyway.
