hi john what you describe is known to us, but unfortunately i didn't find a way to solve it by myself. also the netpd-server patch running on netpd.org crashes from time to time. i am not absolutely sure about the reason and i also tried to debug it by running pd within gdb. therefor i compiled millers pd, zexy and maxlib (the dependencies of the server patch) with debug symbols, but unfortunately it still didn't show me the symbols of the point where it crashed. i am not too familiar with these tools, so probably i made something wrong. from my experience i can at least confirm, that most likely [netserver] from maxlib is the trouble maker. from what i can tell, crashes happen more likely, if several clients disconnect without saying 'adieu'. (http://en.wikipedia.org/wiki/Transmission_Control_Protocol#Connection_termination ) this happens, when internet connection of a client suddenly is lost or if pd of a client crashes. sometimes it doesn't crash for months, when all clients have good connection (an they don't crash too often). i would be interested to know, what conditions are needed to crash pd/server-patch on your box. does it behave the same? if so, i wonder if [netserver] really complies with tcp. i also wonder what host is supposed to do if only one end point finishes the connection (and this what happens, if a client crashes, i suppose). > P.S.
