Hi Subrata,
1. What does top report as the processes's states?
2. Has he tried running strace on the board to see what the
processes are waiting for?
3. Has he tried kill with all signals (until the processes
`unhang' themselves) to see whether or not they're waiting for a
particular signal / event?
Cheers,
-Garrett
