Hi,

Ask your system administrator to have a look at the hanging threads and deploy locks and remove them.

A restart will resolve this...

Hi Satish,

I had faced this some time back.

We figured out, that one of the sessions of the application was active and under tedious processing when we were trying to deploy the new code for the application.

Either close down all the sessions of the application you want to deploy, or, try restarting the Server and then Deploying the application.

In our case, Server Restart worked.

Best Regards,

Alka.
