select() with netos6.3 problem

Has anyone successfuly tried reading from multiple sockets using select() on netos 6.3.
I am having problem, where even though 2 sockets are set, FD_ISSET returns true only for one socket, individually both sockets work if only one socket descriptor is set at a time using FD_SET

Make sure you’re running the latest patches, I seem to recall there was a problem with that at some point that was fixed.
