Connection Pool issue with latest Hibernate Version

HI Team,

We have migrated from hibernate 5 to hibernate 6.4.1.Final, but the it started giving issue like :
‘Unable to acquire JDBC Connection [HikariPool-1 - Connection is not available, request timed out after 30000ms (total=10, active=10, idle=0, waiting=15)] [n/a]’)

Leading to

error = ‘Could not open JPA EntityManager for transaction’)

Same number of transcation (Code) and connection pool are being used with Older version (Hibernate 5) but without an issue.

Has there anything being changed which is causing higher number of pools being utilized? and is there any general suggestion that could help to solve the same?

No, there were no changes that should affect this. If you want more help, we need more details. Ideally, you would try to create a reproducer with our test case template and if you are able to reproduce the issue, create a bug ticket in our issue tracker and attach that reproducer.
