In Linux if we call blocking recv from one thread and close for the same socket from another thread, recv doesn’t exit.
Why?
Check that all file descriptors for the socket have been closed. If any remain open at the “remote end” (assuming this is the one you attempt to close), the “peer has not performed an orderly shutdown“.
If this still doesn’t work, call
shutdown(sock, SHUT_RDWR)on the remote end, this will shut the socket down regardless of reference counts.
