After updating servers from powerbroker to centrify on the AE server, processes were restarted. AWI showed that RestEndpoints were not available which points to the JCP and/or JWP being unavailable. When attempting to start them, the following message occurs in the logs sometimes:
20210731/160914.492 - 1 U00003545 UCUDB: Opening database ...
20210731/161119.975 - 1 U00003611 DB OPEN executed. Return Code = '17002'
20210731/161119.975 - 1 U00003590 UCUDB - DB error: '08006', 'IO Error: Connection reset', '17002', 'java.sql.SQLRecoverableException'

Also attempting to run the ucsrvjp -setup throws the following, again, sometimes:
JCP and JWP will not start from service manager, but will start sometimes (anywhere from 1 in 5 attempts to 1 in 10 attempts) with nohup command.
Release : 12.3
Component : AUTOMATION ENGINE
Other admin teams need to be heavily involved to troubleshoot the full stack to see what exactly is happening between JDBC and the database
