Hello Meena,
There may be many reasons for the tread getting stuck in the websphere;
If the tread created for a request is processing something or waiting for a resource, it would be
visible in the log files. It also indicated in the KBA 1682707, it may also be due to low query
optimization on the database.
Once the limits of the thread is reached, the websphere may be hung; you can increase the limits of
the thread as follows;
1. Launch websphere administration console and login as Administrator. Navigate to server --> thread pools--> webcontainer--> increase maximum threads setting as required.
Also disable thePMI:
Navigate to application servers--> server---> performance---> performance monitor infrastructure (PMI). Uncheck the option "Enable PMI" to disable PMI.
Thanks
Willie
