[EBUSY]
    Resource busy.

    An attempt was made to use a system resource that is not available at
    this time.

    The open sharing mode may conflict with another open of this file, or
    O_WRONLY or O_RDWR is specified and the file is checked out by another
    user.

My guess is that it's just a timing problem.   Your process is trying to
open a file for read/write when an existing process already has the file
open for read/write and hasn't yet closed it.

I assume that your system is designed to open the file, read/write that
file, and then close it immediately.   If so, that's why trying it again a
second later solves the problem.   It also explains why this happens only
rarely.

My application is an interactive app...  it just tells the user about the
problem, and the user tries again later.

In your situation, I think I'd wait a second and try again (or perhaps
less than a second) Possibly have it try for 5 seconds, then give up...

Good Luck
