Consider scanning /proc/<PID>/fd/* or using lsof to see if the server process still has the file open.

Or, more simply, if you can trust that the filesystem will be local, make use of mtime. Yeah, it's not perfect but you can wait for the file to be 15 seconds stale and it will work as well as the other hacks.

Independently, it may be simpler to use fuser for a single file inquiry than lsof. Personally I generally struggle with the lsof flags, but I may be the odd duck.
