Ahhh.. your postfix is misconfigured, I think. It's trying to hammer lmtp 
with 850 different (simultaneous?) LMTP connections. It ought to be able 
to send them down a single connection--and if it's the same e-mail with 
the same return-path you just need 850 RCPT commands, and Cyrus hard-links 
them for you :) I do this with Exim with "batch_max=1000"; I'm sure the 
Postfix equivalent can be found by searching the archives even of this
