My NeXTdimension Turbo and another NeXTdimension Turbo are suffering from  
a strange behaviour which causes system panic more than twice a day!!
The /usr/adm/messages and console simply reports "mach panic ... No more  
room in kernel map" and the system dies. Sometimes without syncing which  
causes some other problems!

For further information: There are no special programs running, but the  
systems are running the whole day and are fileservers. We do not log out  
more than once a day (or because of crash). The systems are sometimes  
heavily loaded.

Any comments or suggestions????

- Bernhard

Heavily loaded, eh?  If you run out of processes or threads, the
kernel will go down in flames...  It's really, _really_ stupid, but
thats what happens. (although I think you'll get a "proc table
overflow" panic if that happens...)

Just comments:

I have a 25 MHz NeXTdimension and I have had at least four of these exact panic  
messages.  The first three happened every time I was printing, but now that  
I've run the PrintManager I can print.  The most recent happened today when I  
clicked on a posting in rec.music.synth which NewsGrazer mistook for a  
NewsGrazer posting (it showed a standard text file document in the Article).

My machine has NOT been heavily loaded at these times!
