Hello,
I have been running some tests on a new Dovecot v1.0.13 server and have seen the following message appear in the logs a few times. It appears to occur when there are a lot of requests being sent to the LDAP servers from both Dovecot and Sendmail (I am guessing about this, since I have also seen "Server busy" messages regarding LDAP auth).
dovecot: auth(default): file db-ldap.c: line 310 (ldap_conn_retry_requests): assertion failed: (conn->connected) dovecot: auth(default): Raw backtrace: dovecot-auth [0x806daf1] -> dovecot-auth [0x806da0c] -> dovecot-auth [0x8059607] -> dovecot-auth [0x8059b1d] -> dovecot-auth [0x8059b7b] -> dovecot-auth(io_loop_handler_run+0x110) [0x8070c90] -> dovecot-auth(io_loop_run+0x1c) [0x80701cc] -> dovecot-auth(main+0x2fe) [0x805b01e] -> /lib/libc.so.6(__libc_start_main+0xdc) [0x3efdec] -> dovecot-auth [0x8051161] dovecot: child 23178 (auth) killed with signal 6
Dovecot seems to recover from this error and continues to handle auth requests properly.
Thanks, Eric
