Stopping core dump

dictum9 — Fri, 21 Dec 2007 19:36:46 GMT

I have this 11.0 box that keeps dumping core, apparently due to SSH (as file core reveals)

I would like to set core size to 0, so it doesn't dump core anymore, how do I do that?

so, ulimit does not exist in 11.0

Per advice, I did:

touch /core
chmod 444 /core

This means a new core dump should not be able to write to this one.

This is incorrect. It exists in sh but not in ksh. Both are real shells.

>Per advice, I did: touch /core

I would suggest you use "mkdir core" instead. It is more obvious.

AS Dennis indicates, the standard POSIX shell (not Bourne) has ulimit -c. The problem with mkdir is that you have to do this in every possible directory that a core might occur -- kind of hard to predict. ulimit sets the environment and if you are using ksh, there are many ulimit values you cannot set in ksh. However, you can change your shell to /usr/bin/sh with the chsh command, then add the ulimit line in your .profile and at the end of .profile, run ksh. (you will find the POSIX shell is almost identical to ksh so the last step may not be necessary)
