Disk Space disappears: 2 big cPanel files?

[teakwood]

I noticed disk space usage in my VPS doubled overnight earlier in the week.

Trying to find the cause, I discovered two 2-Gig files, located in /usr/local/cpanel/whostmgr/docroot, called core.24070 and core.25225, created 1 minute apart on Tuesday.

My other VPS had a less dramatic space usage jump. It has one 2-Gig file, core.16939, created at a similar time.

My dedicated server doesn't have one of these mystery files. (all three do have a file called core, which looks a much more normal size).

I seem to remember updating WHM on the VPSs, which may have been the reason.

Anyone have any idea what these files are, and what might happen if I delete them?

These are core-dump files that are created when there is a segmentation fault in an application. Most likely cPanel segfaulted and created those.

They are for debuggin purposes only, so they won't be of any use for you and you can delete them.

I would have picked them as core dumps if they hadn't been so big, but I guess the VPS gets to dump everything available to it including the "burstable" RAM?
