Hello everyone, For this installation I am using passdb against AD, userdb with MySQL and nfs storage but using simultaneously the vfile acl backend and the shared mailbox dictionary I get the following panic: Oct 19 12:34:51 server dovecot: imap-login: Login: user=<user04>, method=PLAIN, rip=10.112.99.52, lip=10.113.63.50, mpid=7538, session=<NKsDsnIiU7YKcGM0> Oct 19 12:34:51 server dovecot: dict(7540): Panic: file dict-sql.c: line 670 (sql_dict_iterate): assertion failed: ((ctx->flags & DICT_ITERATE_FLAG_ASYNC) != 0) Oct 19 12:34:51 server dovecot: dict(7540): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0() [0x31826800ca] -> /usr/lib64/dovecot/libdovecot.so.0() [0x3182680136] -> /usr/lib64/dovecot/libdovecot.so.0() [0x31826299ea] -> dovecot-mailbox/dict() [0x406abc] -> dovecot-mailbox/dict() [0x4047aa] -> dovecot-mailbox/dict() [0x404f32] -> dovecot-mailbox/dict(dict_command_input+0xab) [0x4050bb] -> dovecot-mailbox/dict() [0x40425b] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x5b) [0x3182692deb] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xb7) [0x31826943c7] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x25) [0x3182692e95] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x3182693038] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x318262e953] -> dovecot-mailbox/dict(main+0x165) [0x405295] -> /lib64/libc.so.6(__libc_start_main+0xfd) [0x303be1ed5d] -> dovecot-mailbox/dict() [0x403da9] Oct 19 12:34:51 server dovecot: dict(7540): Fatal: master: service(dict): child 7540 killed with signal 6 (core dumps disabled) am I missing something obvious or this is a dovecot bug?
