[comp.sys.ncr] Hanging processes on the Tower

Help!

I have noticed on occasion that processes on the NCR Tower will hang.
Generating a ^C will not stop them, but the stronger interrupt (^\) 
will kill the process and create a core dump.

I usually see this when I have two or more processes running that are
fairly big tasks. For example, yesterday I was running a recursive
make command which usually takes about 30 minutes to run and at the same
time a tar tvf of a large number of files. Both tasks hung and after about
an hour, I killed the tar. The make was still hung and I had to kill it
also.

I am running on a NCR Tower with the 68020 processor. It has 16MB of
memory. Could this problem be related to swap? Why do things simply
hang? I am able to use the kill command to kill the processes (kill -9),
but I don't understand why they get in the state they get in.

Any ideas anyone?
