Open File Cache is not likely related to this problem. Open file cache was
designed to address performance problems with
batch files. When windows clients execute batch jobs, the sequence of
events is something like "Open file, read line, close file, process read
line, Open file, read next line, close file process read line, etc". Rather
than having VMS close the file each time the client says to close, the Open
File cache provides a mechanism to keep the file open briefly, essentially
betting on the fact that there is a good chance the client will want to open
that file again, real soon.
