Hi Jeff, Thanks for your reply . Could you please share some sample code with the usage of setsockopt() if possible?

Try using setsockopt() to set an appropriate receive timeout value, then check the read function return value for EOF.

Unfortunately I'm using now RTOS and raw API, so I don't think I can help you. Most probably, other users will reply with suggestions on how to track and identify your issue.
