All I did was carefully read Jamesday's comments - he's 'the man who knows'!. The current crap-out is because were being spidered by some nasty robot - check out this and look for the cliffs. That's when we're being hit. If we're not being hammered at requests per second are below 1,000 wiki runs sweet! The thing about the edits seems to be the slave database servers not keeping up with the changes on the master. Mediawiki 1.4 accesses the master a lot less, so I'm guessing the slaves aren't being updated as frequently, so even if your change is saved on the master, if you next get a page served by a slave it can be out of date. Possibly!I know for a FACT that this is behind the difficulties in creating new pages - the slaves aren't asking the master when they should. Maybe they should've beta tested 1.4 for longer, but I guess they felt that if they'd stayed with 1.3 the master would've died under the load of the continuing natural site growth.
