Check how often it's checking out and building, and how many processes 
it's starting to do that.  By default CC always checks out the entire 
repository - which is a slow operation - rather than just updating the 
files that have changed since the last build.  In a large repository 
it's going to take a few minutes to do that.. so if you have a checkout 
taking 5 minutes and CC set to fire every 2 minutes.... boom.

If you can, set it to only do updates of the files that have changed 
(cvsnt can do this but I don't know if CC can use already checked out 
sandboxes).  Failing that, slow the rebuild cycle down so there's 
breathing space... depends on your load patterns how much you need really.

btw. tagging is quite slow, so if CC is doing a tag before build you 
have to take that into account in your calculations (this will hopefully 
be fixed early in the 2.6 cycle, but that doesn't help you now of course).
