G'day All, I've got Samba4 using Bind for its DNS, and all seems to working well, except that I've noticed occasionally that bind either dies or locks up. I see the following in the my named.log file: 02-Jul-2015 21:54:08.859 database: critical: samba_dlz: talloc: access after free error - first free may be at ../lib/ldb/common/ldb.c:1592 02-Jul-2015 21:54:08.859 database: critical: samba_dlz: Bad talloc magic value - access after free I have this set up running on Centos6 and it hasn't been a problem. Not sure if it's the OS, as C7 is significantly different to C6 in quite a few ways..... -- Cheers, David Minard.
