Hi, my samba server crash a lot, after upgrade from 4.1.x to 4.3/4.x (no problem before, running 4.1.x version)
(my system is running amd64/current with samba package 4.4.3p0) I found some error message in "/var/log/samba/log.smbd" like this: [2016/05/28 09:37:30.217939, 0] ../source3/lib/util.c:791(smb_panic_s3) PANIC (pid 27088): internal error [2016/05/28 09:37:30.218145, 0] ../source3/lib/util.c:902(log_stack_trace) BACKTRACE: 1 stack frames: #0 0x18b8b840d51e <log_stack_trace+62> at /usr/local/lib/libsmbconf.so.0.0 And "dmesg |grep signal" message like this: crash of smbd(69427) signal 6 crash of smbd(47833) signal 6 crash of smbd(79506) signal 6 crash of smbd(18370) signal 6 I can not find any core dump file in /var/log/samba/cores/ and else where. Attached testparm and /var/log/samba/log.smbd file here. Any idea, how to solve / debug? Thank you.
