Which specific svn version are you using? 7385 contain changes
to make sure that only 20 events are put into the database each
run through. 7386 reduced the priority of the scanner and sched.
This greatly reduced the load on the DB from what it was previously.
I'll look at what else I can do to reduce the DB load some more.
