Table locking during login due to SQL updates is bringing down production environment under heavy load due to the following SQL statement:
SELECT VERSION, OBJECTTYPENAME
WHERE OBJECTTYPENAME IN ('CRM', 'PRUH') FOR UPDATE OF VERSION;
The normal response time for the response from the PSLOCK table is .003 seconds but under heavy load we now see responses upwards of 30+ seconds for users to login. During this performance issue no users can login and eventually the app servers crash.
