What passdb and userdb are you using? Could you attach gdb into one of
those processes and run these commands:

p clients.nodes_count
p main_refcount 
p ssl_proxies.nodes_count
p *auth_connections
p auth_connections.requests.nodes_count
p master_requests.nodes_count

I looked through the code and all I can think of is that either auth
process doesn't reply to some request or master ignores the request to
launch new imap process..
