[Dovecot] Dovecot v2.0.beta6 - child ppppp killed with signal 11

[Mark Sapiro]

Since upgrading from 2.0beta5 to beta6, I have seen a few pairs of log
messages like the following:

Jun 13 15:57:17 sbh16 dovecot: imap-login: Maximum number of
connections from user+IP exceeded (mail_max_userip_connections=30):
user=<gpc>, method=PLAIN, rip=76.126.100.210, lip=72.52.113.35,
mpid=0, TLS

Jun 13 15:57:17 sbh16 dovecot: master: Error: service(imap-login):
child 16960 killed with signal 11 (core not dumped - add -D parameter
to service executable

The "Maximum number of connections from user+IP exceeded" message is
not new - this is an issue with the K9 mail client on an android phone
- but the killing of the child is new in beta 6. Is this intentional.
