php4.core showing up in unexpected places

[riskynil]

There have been two times so far I've discovered a file named php4.core sitting in one of my directories, but I don't have a clue as how it got there or what it is doing. It's a rather large, multi-megabyte file, and the term 'core dump' keeps running through my head, but I haven't noticed any unusal behavior on my site either. Everything seems to be working just fine.

What would cause this file to drop in out of nowhere? Is it something I should be concerned about?

Thanks!

It's a core dump.
Either your script caused php to go wild, or bug in php itself caused it.
As it can be faulty script of yours causing it, you should monitor logs
and check script if there is something strange.

You can delete that file.
