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?
