Brent,
I understand what is happening. It is because I/O threads lets the
mtime overtake the write call. I assume you have loaded io-threads on
server side (or below write-behind on client side). I could provide
you a temporary 'ugly' fix just for you if the issue is critical
(until the proper framework comes in 1.4)
regads,
avati
