well, some program tried to access inappropriate memory.
note that this _can_ be due to hardware problems (overheating,
bad memory, etc).

for a good reason - the problem is probably particular to the cluster,
not general to the software...

wow, that actually dates from 09/05/2000, at least according to the 
timestamps on the mpich ftp server...
