com.atomikos.jdbc.AtomikosSQLException: Connection pool exhausted - try increasing 'maxPoolSize' and/or 'borrowConnectionTimeout' on the

In my spring batch application, i'm using atomikos version(4.0.4) and JTA(1.1).Some of the jobs are hanged in PROD and acquired all the connections from DB which in turns stopped the other jobs which were triggered in parallel. And all were failed with below error.

Error Log 1:
Could not get JDBC Connection; nested exception is com.atomikos.jdbc.AtomikosSQLException: Connection pool exhausted - try increasing 'maxPoolSize' and/or 'borrowConnectionTimeout' on the DataSourceBean.

Error Log 2 :
Failed to grow connection pool.

And almost for 13 jobs no instance got created in DB and in control-m the logs were captured with "Null Exception Message intercepted"

Can anyone please suggest on this issue? Even tried with upgrading the atomikos version upto 5.0.0 but still same issue occurring.
