Hello Nikunj,
This dump is ofter related to a process which triggered a remote RFC to process a request and deliver some response.
Turns out that this remote processing took too much time (due to a huge selection criteria or some other situation), much longer than expected, and at the time it finished the original caller was no longer waiting for the results and so there was no one to deliver the them to.
This is a consequence of a problem, not the cause. You have to investigate why the processing on the remote RFC is taking so much time to complete.
Cheers,
Ian Segóbio.
