Does anyone know what these are caused by? I can delete them via ftp without any problems to the sites involved.

There's lots of chatter out there about this. Seems to have something to do with PHP memory limit and possibly caching.
The server with the CORE files has 512MB of ram for php whereas the server that doesn’t run out of memory has 90MB. Im trying the smartwebprojects solution.
The php settings should inherit from the root. And while it appears that it was inheriting, my server environment want the repeat of the ini file in each installation root.
Maybe this will help someone else.
