Steps to Reproduce



There is no specific use case to reproduce this issue.


Root Cause



A defect or configuration issue in the operating environment. The maximum connection pool on Websphere was set to 50 whereas the maximum number of users expected is 70.

max connections = 100 
min connections = 50
