OK, here's my VxWorks question of the day:

I'm using a TCP/IP socket (AF_INET, SOCK_STREAM) to transmit messages
between processors on the backplane. Unfortunately, it appears that
for some reason, the last byte sent is not received at the other end.
That is, send() returns 16 (I'm sending 4 ints), and recv() is returning
15. All 15 bytes actually transmitted do arrive correctly, but the last
one is lost. Has anyone else experienced this?
