Aaron, Thanks very much for posting the copy of your test collection. Unfortunately I've still been unable to replicate the problem - and my test computer is certainly far from 'too good' :) So there must be some difference in my setup. I'll try to come back to in a week or so and have a fresh look to see if I can work out what environment details are making the difference. Longer term it would be good to understand what's going on. Until then disabling the transactions (in mysql) should do the trick!

This seems to be an issue unique to MySQL, and it can happen with as few as 2 or 3 concurrent users. It has been reported across all stable versions. Strangely, it seems to be a relatively recent issue (i.e. we never heard this with Mahara 1.8 or 1.7, etc), so this suggests it was triggered by something that changed fairly recently. One possible candidate is our switch to the mysqli driver (before that Mahara wasn't doing transactions at all, in mysql).
