I've got a few servers where I run Samba 4.8 in a jail as an AD DC. Lately, on a couple of them, it started dumping core: on one server, apparently everything works fine after that; on another one I have intermittent DNS issues, but I'm not sure they are related to this core. I tried examining the core, but this is what I get: > # gdb /usr/local/sbin/samba samba.core > GNU gdb 6.1.1 [FreeBSD] > Copyright 2004 Free Software Foundation, Inc. > GDB is free software, covered by the GNU General Public License, and you are > welcome to change it and/or distribute copies of it under certain conditions. > Type "show copying" to see the conditions. > There is absolutely no warranty for GDB.

Samba is compiled (via Pudriere) with DEBUG, so I thought the above would be more useful. Any hint? bye & Thanks av.
