/var filled up with MRTG "core" files

[Stream]

The past 3-4 days the folder /usr/local/apache/htdocs/mrtg has been filled up with files called core.xxxx (where x is a number).

Currently it contains 5.8GB of these files, while another server I have only has 270MB in this folder. Both servers have been running MRTG since April this year.

Anyone knows what these files are and why they are created?

Can I safely delete them? (allthough that won't help much if they keep being created).

Any help would be greatly appreciated!

You can safely delete them. they're created when an executable fails and the OS creates a core dump file which can be inspected with the right tools, but is not straight-forward. You'll need to look into your mrtg procedure to find out why it's failing.

Thanks for your reply, chirpy!

Tried upgrading mrtg today, and now it won't run at all.

Will have a closer look at it later on when I've cleaned up all these core-files...
