Hi
I have a quite obscure problem with DJGPP executables
and the Netware shell (VLM).
Most of the time everything works fine, but occasionally
the connection to my server gets killed. This happens
usually after (or while) running programs that were
compiled with djgpp. Reaccessing the server is impossible,
and I have to reboot.
The basic setup of my machine is

DOS=HIGH,UMB
DEVICE=HIGHMEM.SYS
DEVICE=EMM386.EXE NOEMS RAM HIGHSCAN /some hw areas excluded/

Most of the NW requester is loaded to Extended Memory.
I have the feeling the the problem occurs when I use programs
that use a whole bunch of memory, but I cannot say for sure. 
Starting pgp works fine 5-8 times, then the server connection
is gone. 

As I cannot think of an error that gcc, pgp, mkisofs, less
and others have in common, I belive the culprit is either the
requester or cwsdpmi. I'll check that with a DOS-Box under
windows.
Charles (and the rest), can I somehow figure out what
cwsdpmi thinks  which parts of the memory is in use by 
the requester and which ones are free? I guess that 
cwsdpmi overwrites parts of the requesters memory,
because the launched programs usually finish in the 
expected way (unless they require reading from a network
drive).

Any ideas appreciated.
