If the queue is still building up, something is most likely timing out. 
Are you running Pyzor, Razor, or DCC? Using any odd URIBLs or DNSBLs 
that could be timing out? Several months ago Pyzor timed out (10 seconds 
per message) on me for a while, that really hurt performance. Do a lint 
or debug and see if anything hangs for a noticeable time period as Glenn 
suggested.
