Hi John,

Im sorry to say, but this sounds 'classic': The macppc port has a known  
problem with the serial ports. The serial port driver is known to  
crash, especially under 'heavy' load (displaying a man page can  
sometimes be enough). Best way to solve this, is to make sure you only  
get very spare output on the serial console.

...of course the best way to solve this would be to fix the bug. I'm  
sure you would make quite a few people happy (including me). It's  
something with the way interrupts are handled. Modern macs don't have a  
serial console, so the problem 'will go away by itself' in some way. ;)

/Daniel
