tried touching file & sleeps w/o success
native perl copy command appeared more problematic
switched to unix rsync command which solved the problem most of the time
solved the remainder of the problems by creating a script to compare bytecounts of source & destination files & re-rsync'ing if different
are you by chance using a global or parallel file system ?
