Gah. I'm still thinking in Perl/Tk terms. I was trying to figure out why the filehandle wasn't being picked up as 'still readable' instead of looking for a lower level solution. I've been doing a lot of head slapping lately.... > Unless you're using datagram sockets, there is no guarantee that an entire > message showed up at once, so you always have to be able to handle partial > reads. Partial reads aren't a problem (the main program just buffers the data until it gets a whole message as long as the message so far is structurally valid) it was just that sometimes that 'too big' message wasn't followed by another message for a very long time, so the buffer was never getting flushed. If I use: use Fcntl; fcntl($FROM_CHILD, F_SETFL, fcntl($FROM_CHILD, F_GETFL, 0) | O_NONBLOCK); that should do the trick.
