Unable to Start/Stop Websphere Liberty on Pega 8.1.1

Hi,

We were trying to upgrade Pega Customer Service & Sales Automation to v8.1 and then it got stuck in the middle & now we are unable to start/stop our app server which is websphere liberty. When we checked the server log, we get the below error repeatedly. It seems it has something to do with connection pool but I am not sure how to fix this. our max connection pool size defined in app server is 50 which i think is the max limit and should be enough. Attached is the server log.

J2CA0046E: Method reserve caught an exception during creation of the ManagedConnection for resource jdbc/PegaRULES, throwing ResourceAllocationException. Original exception: Pool requests blocked, connection pool is being shut down.
