Hi Ashish,
If you see the Transitive Graph on the report page, you will see 9 threads are getting blocked by thread fx_lis_3Container0-1, and this thread is stuck in read0() method of sun.nio.ch.FileDispatcherImpl class. If you see the stack trace of thread: fx_lis_3Container0-1, before getting stuck this thread has obtained 4 locks, and due to that 9 threads are blocked.
As per my understanding, while connecting to your oracle database the connection got stuck and never timeout. In order to fix this issue, you may consider setting the timeout while initializing the connection.
