This indicate some kind of a connection leak.. There shouldn't be so many connections. Each login process is supposed to create only one connection to anvil and one connection to ipc. How many open fds do you see in those processes currently?
Oh, this is most likely related because you're not running in high-performance login process mode, unlike pretty much everyone else running proxies: http://wiki2.dovecot.org/LoginProcess
Lets see if I can reproduce this then..
