Hi Monks-

With your help (especially Zantara) I have developed a short perl script that acts like a midi playlist editor. It uses the Tk library for a gui, IO::socket to get messages, and spawns off the playmidi executable in the background with a system("playmidi songfile &") call.

It runs fine for a little while, then after playing a song and being idle, apparently it locks up my whole computer. (no display or ssh access, keyboard lights blink, and cpu gets very warm). I have been using VNC to test the program Its a debian knoppix system, kernel 2.4.26.

Anybody have any ideas about what might be locking it up? Is the latest Tk library or IO::Socket module not completely stable? I've been using this system for over a year, and have never seen it lock up like this, and unfortunately, it doesn't seem like tracking this down will be too easy.
