SmileCdr throwing JDBC connection errors

[reshmi sasidharan]

Hi Team

We are getting "could not open jpa entitymanager for transaction unable to acquire jdbc connection" from SMILECDR while doing concurrent calls to fetch Person resource using the Person/id endpoint. We are doing a load test on our application and getting this error.Its not throwing error when the load is less. Is there any configuration we can use to solve this issue? Please help us finding a workaround. 

Thanks
