Exemgr (sometimes primproc) crashes on large queries with joins in SkySQL and docker. Requiring a restart of the cluster/node to spin exemgr back up.
clients and users see the following when sending additional queries
ERROR 1815 (HY000): Internal error: IDB-2004: Cannot connect to ExeMgr.
A graceful error of the query, ideally with a reason why (need more ram, storage, cpu etc.) that doesn't require restarting services to make other queries afterward.
Steps to reproduced attached along with a video of the crash
