Sounds like a liquibase issue, where it is attempting to create QABPM4.record_list_action_cfg but failed because it already exists. You might want to consult the Liquibase documentation instead.

Hi Edmund,

Can you help what to do when we are getting this type of error.

Yes, somewhat related to database. I think the services were not properly shutdown properly previously, thereby causing errors to one of the database lock tables. I have resolved it by following the instructions here: https://community.appian.com/support/w/kb/249/kb-1024-could-not-acquire-change-log-lock-currently-locked-by-user-error-thrown-during-application-server-startup

This likely means that you are failing to connect to the database. I'd revisit your Appian Primary database connection information.
