  Hi, I'm currently working in an SGI environment and my problem is as follows:
I have a loop in one of my slaves that does a general receive from any source
with any msgtype. It then checks for the msgtype by looking at the buffer info.
and unpacks based on the type of msg.
  Now my problem is that in the first iteration everything works fine, but the
second iteration the pvmfrecv doesn't seem to be blocking and returns with an
invalid msgtype = 0 (I never send 0 type msgs). This obviously causes some
errors as there isn't a message in the buffer.

Thanks
