So if it happened on this small thread then what is the difference between this and a long thread ? I would seem that this would be dependent on how many posts were veiwable at once. In this case almost the max of 90+
It has to do with the need for the system to end up doing a full table scan that doesn't mesh up with the index on the table.
It is a glitch, it will probably be fixed in the future, but for now it is a problem which makes it that when threads get too big we are going to have to lock them if we have to often go in and moderate them.
It is better than a few years ago, when every thread would need a "Thread 2" after a few hundred posts, though.
