The backend server didn't reply within LMTP_PROXY_DEFAULT_TIMEOUT_MSECS (30 secs). It still shouldn't have crashed of course, and that crash is already fixed in v2.1 (in the LMTP simplification change). Anyway, you can fix this without recompiling by returning e.g. "proxy_timeout=60" passdb extra field for 60 secs timeout.
