If "mostly happens when a show changes", from what I've read on the
dev list in my research you might want try putting the mysql database
on a different disk.  It seems the scheduler query is quite intensive,
and runs during show changes.  You're already using a lot of disk i/o
with HD, then the query runs and *could* be a cause of this.  I'm
getting this on SD, and not just on show bounds (on top of that I have
no other place yet to test having the db)

So from what I'm reading this seems like a general symptom of
performance problems, of which could be any number of things.
