[Samba] Samba is still crashing
I have had a problem for a couple of weeks now. I get very regular crashes on two of my three Domain Controllers. I just updated to 4.1.0 and I am still getting the same problem. I have added panic action = /bin/sleep 9 to my config. Here is a back trace for the crash.

Re: [Samba] Internal DNS CNAME not working
I upgraded to 4.0.4 and still did not have any success with CNAME records. As it turns out the problem was the syntax I was using to create the records. You need to include the full domain name and the period at the end. I think the samba-tool should validate these CNAME records when adding. Does anyone think that this raises to the level of a bug? bad bin/samba-tool dns add 127.0.0.1 mydomain.com my-server CNAME samba-001 -Uadministrator good bin/samba-tool dns add 127.0.0.1 mydomain.com my-server CNAME samba-001.mydomain.com. -Uadministrator Wayne Andersen System Administrator Clima-Tech Corporation 208-947-1849 -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

Centos 6.4 64bit I have just sent the details of strace and dig, in a separate mail Frankly I do not know how to read the results. dnstracer -v my-server.mydomain.com fails with, return code 3 (Name error) dnstracer -v -q cname my-server.mydomain.com succeeds, returns Resource data (9)samba-001 It looks like my resolver only checks the local dns for A records.
