I had a tough time once last year (being then a novice in the world of
UNIX 4.3 BSD sockets) trying to figure out why my distributed matrix
multiplication program hung up for big problems (with higher number of
non-blocking calls to remote servers). Experimenting with different sizes
of matrices (and blocks), I found that the problem arose after about
fifty client-server stream (connection-oriented) connections.

The problem was in my leaving the sockets open, even after the client had
successfully demanded the result. Yes, it was the wrong way to look for 
errors. But .......

I was using TCP/IP on the DEC 2100s here.
