Hi, I don't have anything particularly useful to add other than to say I have seen this issue 'in the wild'. I didn't have time to investigate the issue, so I just set the number of threads used by the pager back to 1 to get a demo out the door (which obviously stops the problem occurring). I have seen the pager deadlock on a range of hardware, all running windows XP, and all using VPB generated terrain. I was only using 2 http threads so it didn't occur often (maybe once an hour).
Let me know if I can help with the issue at all as I would like to try and get it resolved (even though I had completely forgotten about it for now).

The paged .ive is about 7GB and I use 4 DatabasePager threads. For recognizing the deadlock I press pause from time to time in the debugger and look if multiple pager threads are stuck in a lock.
