Since we had it done, one of our machines runs like a dream, no tbuf panics, nothing. The other, which used to run without a crash between maintenances, now crashes every now and then with a 'wtimo' panic (write timout to memory). The first machine has all DEC memory, the second has 1M DEC, 3M National Semiconductor. Like Gene's machine, it seems to die under heavy load. Does anyone know what the junk pushed on the stack with a write-timeout error means? Is it any use in finding which memory board was in error?
