The backend server didn't reply within LMTP_PROXY_DEFAULT_TIMEOUT_MSECS (30 secs).
It's actually 60 sec in v2.0
http://hg.dovecot.org/dovecot-2.0/file/750db4b4c7d3/src/lmtp/lmtp-proxy.c#l13It still shouldn't have crashed of course, and that crash is already fixed in v2.1 (in the LMTP simplification change).
Do you think we should rather run v2.1-rc* on our dovecot directors (for IMAP, POP3 and LMTP), even if we keep the backend servers on v2.0 ?
Anyway, you can fix this without recompiling by returning e.g. "proxy_timeout=60" passdb extra field for 60 secs timeout.
Thanks, well consider that option if it crashes too often... Have only seen this problem once for the last week.
