Files are not deleted handle held by system process

We have deplaoyed our application on may servers but on only one we

are seeing a strange problem. The application is written in C and

uses the remove function to delete a file.

The file appears to be "almost" deleted - we cannot open it, copy it

or view security attributes etc but a di in the folder shows it is

still there.

We used process explorer to look at it and it reports that the file

has on open handle from the system process. If I right click in

process explorer and select "close handle" the file disappears.

Any idea why the file is not removed?
