Hello,
this problem still persists in beta9. I took backtrace for it(with beta9):
Program received signal SIGSEGV, Segmentation fault. log_unref (log_io=0x0) at log.c:268 268 i_assert(log_io->refcount > 0); (gdb) bt #0 log_unref (log_io=0x0) at log.c:268 #1 0x0804c193 in dict_process_destroyed (process=0x80769d0, pid=14881, abnormal_exit=false) at dict-process.c:168 #2 0x0804bd2d in sigchld_handler (signo=17, context=0x0) at child-process.c:160 #3 0x08059fe7 in signal_read (context=0x0) at lib-signals.c:91 #4 0x08059a21 in io_loop_handler_run (ioloop=0x8075960) at ioloop-epoll.c:201 #5 0x08058dc9 in io_loop_run (ioloop=0x8075960) at ioloop.c:305 #6 0x080516c0 in main (argc=1, argv=0xbff5a624) at main.c:497

Hello,
dovecot crashes when it receives -HUP signal. It happens always if there was some activity - for example, if I start dovecot, check any account through POP3 and then send -HUP to dovecot process, it crashes with the following log entry: segfault at 00000008 eip 0804d3fb esp bfdd3860 error 4 If there were no activity at all since starting, it does not crash.
my dovecot -n output: # 1.1.beta8: /usr/local/dovecot/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local0 protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/pop3-login login_greeting: Server. login_process_per_connection: no login_process_size: 64 login_processes_count: 5 login_max_processes_count: 32 verbose_proctitle: yes first_valid_uid: 95 first_valid_gid: 95 mail_uid: 95 mail_gid: 95 mail_location: maildir:~/Maildir mail_debug: yes dotlock_use_excl: yes fsync_disable: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins: quota mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 apop cache_size: 4096 cache_ttl: 28800 cache_negative_ttl: 60 user: doveauth verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: dict:::proxy:/var/run/dovecot/dict-server:quotadict dict: quotadict: mysql:/usr/local/dovecot/etc/dovecot-sql-dict-quota.conf
