It looks like we have a user on one of our servers that is uploading large files on the server. This is filling up the /tmp directory with several 190MB files. I don't know how they are being uploaded, since PHP max upload size is set to 2MB. They appear to be being uploaded through Apache, since the files have nobody as the owner (what apache runs as on the server). Is there a way to determine who is uploading the files? Anyway to stop it? I'm going to try disabling file uploads temporarily through the php.ini file and see if that stops it, but I would still like to know who is uploading the files.
