NetBSD gizmo 1.4.1 NetBSD 1.4.1 (KERNEL) #0: Sun Sep 12 22:36:26 CEST 1999     r

Some processes (mountd, httpsd, login...) crash and are not killable by
a kill -9. 

Here is ps -axl output for thoses processes
 0 25546     1   0 -18  0   136    0 uvn_ge DWs  ??    0:00.12 mountd

No idea about how thoses processes appear. As the system is running, new 
unkillable zombies processes appear. After 25 days of uptime, I had 5
mountd, one httpsd and one login that could not be killed. I had to
reboot the machine to get rid of them.

No fix known.
