Is it possible you have reached the maxchild limit?

today i've runned into a very suspicious problem never seen before:

While any other IMAP and POP3 ports with and without SSL / TLS are
working -  connects to imaps (993) just hangs, there is nothing in the
logs and a

        openssl s_client -connect mail.myhost.abc:993

just brings out:

        CONNECTED(00000003)

what times out after minutes. Connection to 995 (POP3s) works perfectly.

A imtest -v -s against the IP of the machine hangs on:

...
I tried to delete tls_sessions and even connecting to localhost (where it
is  bound too). netstat shows ESTABLISHED on such connections too.

The service is configured (and worked until tonight!):

  imaps         cmd="imapd -s" listen="imaps" prefork=0 maxchild=150
