Hi, create a directory named core. And core files will not be created.

Sorry, this directory must be created in the same place where core files appears.
This do not solves the cause of core, but left your disk clean.

I hope it help you !

WE have symbolic links in the directories they most ocurr in pointing to /dev/null - this way no corefiles left around hogging disk space.

eg.
/home//*
/tmp
/
and application directories.

eg. ln -s /dev/null /tmp/core

If you're using the POSIX shell, i.e. /bin/sh as your default shell, you can also use ulimit to change the max size of the core file to 0 blocks, i.e. no core:

in .profile add:

ulimit -c 0

patch your app!

# file core

figure out what it went down on and what core'd

get the Wildebeest debugger
from hp.com/go/languages

# gdb /path/to/cored/application /path/to/corefile/core

to look at the stack.

Search on the itrc for some of the signal/stack strings and apply the patch.

remove the core and never get the same one again!!!

or ln -s as above (good for webservers and less maintained directories)

Later,
Bill
