I'm using lwIP, but the calls should be similar for other IP stacks. For
reference, see

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

Sounds like you are not detecting that the connection has been lost. Try using
setsockopt() to set an appropriate receive timeout value, then check the read
function return value for EOF.

I'm using LPC1788 for a product that is in full production for a couple of
years without many problems.
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.
