[mod.computers.vax] 8600 Memory Upgrade

SIBLOCK@MCMASTER.BITNET.UUCP (04/02/87)

Hi again.  I've just doubled the memory of our 8600 from 16Mb to
32 Mb, and ran AUTOGEN.  No UAF parameters (WSxxx, etc) have been
modified yet.   Everything runs fine, except some very large
Fortran application programs (Gaussian-82, for example) don't
run anymore.  It bombs out with a %LIB-F-INSVIRMEM, insufficent
virtual memory error.  This seems ridiculous at best.  AUTOGEN
didn't seem to do anything out of the ordinary.  VIRTUALPAGECNT
is correct (twice what it used to be).  Any ideas, experiences, etc.,
as to why this fatal error would occur?  Things run fine with 16Mb.
(By the way, TSC has not been able to figure this one out)
We're running V4.5, Fortran V4.5.
