Hi everybody,
I've here a big problem!

During executing of big programs, NetBSD hangs up.
The system simply stops. At X11 it's possible to move
the mouse pointer some seconds before he also 'hangs'.
At most (nearly everytime) the HD-LED is on.
I don't know why! I can't reproduce any of the 'hang ups'.
One time it hangs, an other time it runs.
But in most cases it happens after starting big programs.
For example kernel compile under X11 - impossible .
I've compiled an new kernel with KBDRESET set, so I can
flush an ktrace.out on HD after the system hangs.
So I was able to ktrace an Ghostview session before one
of the crashs. Here are the last lines from the kdump.:

   196 gv       RET   select 1
   196 gv       CALL  ioctl(0x3,FIONREAD,0xdffe834)
   196 gv       RET   ioctl 0
   196 gv       CALL  read(0x3,0xdffe838,0x20)
   196 gv       GIO   fd 3 read 32 bytes
       "\M-! Db\^A\0\0P\0\0\0\M-Y\^A@\0\^B\^A\0\0P\0.`\0\0\0\^Fp\0\0\0\^A"
   196 gv       RET   read 32/0x20
   196 gv       CALL  select(0xe,0xdfff0c8,0xdfff0e8,0xdfff108,0xdfff154)
   196 gv       RET   select 0
   196 gv       CALL  ioctl(0x3,FIONREAD,0xdffe988)
   196 gv       RET   ioctl 0
   196 gv       CALL  write(0x3,0x2d000,0x10)
   196 gv       GIO   fd 3 wrote 16 bytes
       "\^B\^A\0\^D\^A\0\0P\0\0@\0\^A\0\0I"
   196 gv       RET   write 16/0x10
   196 gv       CALL  ioctl(0x3,FIONREAD,0xdffe988)
   196 gv       RET   ioctl 0
   196 gv       CALL  gettimeofday(0xdfff158,0)
   196 gv       RET   gettimeofday 0
   196 gv       CALL  select(0xe,0xdfff0f4,0xdfff114,0xdfff134,0)

I hope anybody can help me. Or what shall I do, to find the fault or 
make a better error report ?

Thanks for help.

Before I forget it -- my system:

A2000
GForce 030/50 16MB ( 32MB swap )
Piccolo SD64 / 4MB -> ite3 is console
NetBSD 1.2 / X11R6.1

Again thanks

	    Ingo
