Thread:Project:Support desk/I have over 120GB of core.xxxxxx files/reply

Hi!

These files do not belong to a default MediaWiki installation. They are core dumps, created because your PHP process somehow crashed during execution. I would keep a few of the newest ones and remove all older ones. If you want to know more about your actual problem, you can analyze the files with a program like gdb. Otherwise, it might be worth poking your host about it as it could indicate a misconfiguration of PHP.
