Hi, I've got a new Tyan S2462 with dual AMD MP 1800+'s and a gig or two of RAM, which is being used to provide shell services to some users who have a variety of applications running. It's virtually identical to another that I got and love, which is being used for Usenet news stuff. However, after the machine has been up for a while (variously from several days to as long as a few hours), the load starts shooting up, it develops some processes that show as "R" in ps, but are unkillable, and the following pops up in messages. Apr 7 00:47:53 server /kernel: kernel trap 9 with interrupts disabled Apr 7 00:48:24 server last message repeated 552 times Apr 7 00:50:00 server last message repeated 1861 times Apr 7 00:50:00 server /kernel: kernel trap 9 with interrupts disabled Apr 7 00:50:31 server last message repeated 537 times [etc etc etc] That appears to be #define T_PROTFLT 9 /* protection fault */ I did some searching and it appears that this trap sometimes happens with the Linux emulator, but that's not loaded. Any suggestions as to how to go about debugging this? From the source, I see two locations in machdep.c where it could also be caused... -- Joe Greco - sol.net Network Services - Milwaukee, WI - http://www.sol.net "We call it the 'one bite at the apple' rule.
