How to disable or restrict core dumps

[Jonathan Grymes]

I have an HPUX 11.23 Itanium system.

Shalom,

ulimit -Sc 0

or

ulimit -c 0

This will limit core dump size to zero bytes thereby preventing them.

Put it in /etc/profile to handle the problem globally.

Note that sometimes application vendors need core dumps and you can override this setting for individual users.

another way

SAVECRASH=0
in "/etc/rc.config.d/savecrash" file

[Dennis Handly]

You can also disallow core files by doing "mkdir core" for each directory, if a small number.

For 11.31, there is coreadm(1m).

> SAVECRASH=0

Note: this has no effect on core dumps. This value refers to HP-UX crashes, not core files from programs. Setting SAVECRASH=0 means that a system crash cannot be diagnosed (and therefore fixed and prevented in the future).
