Hi Bart,

Yes I was indeed testing the new async functionlity. MT sync (block/file)io is working fine, as it always has. On the ESX side I see messages repeating like:

Hi -Sietse,

That's unfortunate. I think the newest code in your setup is
asynchronous I/O. Have you already tried to verify whether synchronous
I/O with multiple threads works fine?

Bart.
