Hi there,

I have a problem with the NetBSD-1.0 release on my machine:

486DX-33 VLB
16 MB RAM
HD Conner CFA 540A
#9 GXE level 12 VLB (2MB VRAM + 1MB DRAM)

I get frequent crashes when the machine is heavily loaded and swapping.
Usually it is freezing instantaneously with the HD-led on or it resets itself.

This happens every time when I view a large Postscript document ( > 70 pages)
with Ghostview 1.5 and Ghostscript 2.6.2.
Same effect also when I process a large bitmap with Xloadimage. 
etc... etc...


I never got any message or syslog-info except once:

Is this a swap problem, is it not swapping "fast" enough ?

I dont think it's a swap overflow, it was never used up more than 42%
(at least that's what the last "pstat -s" tells me just before the crash)

The filesystem is an upgrade from NetBSD-0.9 and the kernel is a slightly
modified GENERICAHA

Below are the config file, disklabel and boot messages :
