I'm on version 8.2 and not all the problems have gone away.
All I can do right now is just trap the error and retry...
Gets bogged down after a while. Not sure how much of a limitation the hardware
is but 6 users and I start to run into a deadlock almost every 10 seconds.
I rarely need to go to 6 users, but it's interesting to see what happens when I do.
I'm finding the length of time necessary to wait for a retry can very a lot.
But I'm open to suggestions.
