Hi Maxime, Please provide more details on the perceived problem, or test case ideally …
As development don’t see the problem indicating that basically, the isCriticalError() is used for checking Connection exceptions, if exception is critical the connection is closed and removed from pool immediatelly, but all other connections in the pool are checked with a "select 1” query. Thus if a connection was corrupted, it will not be reused from pool and will be closed after checking with query "select 1”.
