Why would I be seeing a million of these?

Two servers were working fine and then all of a sudden this morning bam 500 load and theres a million dovecots and tons of these lines in the logs.
It is like everyone gets up at exactly 8:30 and hits the pop3 server at once.
Anyway, dovecot 1.1.5, nfs mount, debian lenny/sid amd64, 2.6.26-1-amd64 i had the performance mode options for login configured, i just set back to the single process per login though, I think that hasnt fallen over that way but I really dont remember anymore. I included the dovecot -n using the suggest performance login settings? Do I have something totally out of whack?
