First, thanks to everyone who responded to my questions about
unhooking SCSI devices while the machine was still running.
I guess I won't be trying that anytime soon. :-)
Another question: We recently had a system crash due to
a user running a shell script that accidentally invoked
itself.
$ cat foo
cd /somewhere-else #directory did not exist.
./foo
Is there
1. A way to keep this from crashing the system?
2. If the system has crashed, to determine that
this was the reason?
We are running SunOS 4.1.1.
Thanks in advance,
Mark.

A way to keep this from crashing the system? You could do something like this, which we invoke from /etc/rc.local #!/bin/sh #kpatch: apply local patches to the running kernel # set max per-user processes to 200 N=/vmunix D=/dev/mem adb -w -k $N $D <<\EOF maxuprc/W 0t200 $q EOF #!/end >2.

If you have a dump, looking at the process table with ``ps'' should show hundreds of copies of the shell script running. >We are running SunOS 4.1.1. -- -Gary Mills- -Networking Group- -U of M Computer Services-
