That is very interesting. I wonder if you are accessing files on
these machines in a manner that is avoiding many of the issues we're
having with file locks. On our platform, we find that we inevitably
end up with stale locks left on some files, especially after writing
to them. These locks tend to remain stale for a few seconds or so
before they are finally removed. In that time, we get a "in use by
another process" error when trying to delete them.
Our solution has been to open the files with the FILE_SHARE_DELETE
flag in order to avoid this error. However, the error still remains
with the SmbComDelete command. I believe this is because SmbComDelete
will not allow a "pending delete", resulting in its failure. When we
delete by setting the 'delete file on close' flag, via the
SetFileInformation command, we are actually setting a "pending delete"
to occur when no more handles are open on that file. If the file is
not open by any other process, then the delete occurs as soon as we
close the file after setting the flag.
