Same problem here. We have now 2 DCs. PDC was upgraded from 4.2 to 5.0 and then 5.1. Afterwards we added new ADC - pure 5.1 installation.
Although ADC can resolve any hostname that PDC had configured, they are not showing in ADC webadmin.
PDC is throwing error you both mentioned on DNS (re)start or edit. If I add any new record to PDC, it throws error. Said hostname is shown in PDCs webadmin, but it's not resolving.
If I add new record to ADC, it succeed without any error and both DNS servers are able to resolve hostname, but I can't see it in PDCs webadmin.

It looks like upgrade from 4.2 to 5 broke DNS.

It turned out I put ADC FQDN in Domain controller FQDN field, but should be PDC FQDN. I feel silly, but I'm glad it works now.

We have exactly same problem, except our primary DC is another Zentyal 5.1 server.

Hello,
i have similar warnings on Zentyal 5.0 Developer, but it says that backup was Successful. I didn't try the recovery yet.

Did you solve the problem?

Hello @jfaria,
the same situation with lots of net cache flush happened to me . When you removed this line from cron, was it ok?

Thank you.

Directory and Authentication / Re: Zentyal 4.2.2 samba high memory usage
« on: October 10, 2016, 04:21:41 pm »
Hi segelfreak, all
it is great that we are not alone with this issue. As I stated we have more similar zentyal servers (same zentyal version, same samba version, same kernel different users) and just one has this problem.

I checked the dns.keytab and error in logs, but i didn't find any of this error and my dns.keytab looks fine:
Code: [Select]
-rw-r----- 1 root bind     797 okt 28  2015 dns.keytab
I did further investigation what is different with these processes and found util pmap (which lists memory usage of process), but i am not any wiser:
It looks like this:
Code: [Select]
# pmap -X 15098
15098:   samba -D
         Address Perm   Offset Device   Inode    Size    Rss    Pss Referenced Anonymous Swap Locked Mapping

                    ...................

and problematic is the heap which uses actually 752MB RAM out of 1,3GB of whole process and getting bigger. When I used pmap -XX i didn't get more info, and with pmap -x i just received info that it is anonymous and "dirty". It looks like samba is using memory for something and doesn't cleanup. I can't get any more info.

If you have any tips which tools use to troubleshoot, i am open to any suggestions. Till that, we need to restart the samba service every 3 days.

Directory and Authentication / Zentyal 4.2.2 samba high memory usage
« on: October 05, 2016, 12:17:08 pm »
Hi all,
we have a problem on one production server zentyal 4.2.2 running as PDC, VPN server and file server (no exchange) with high memory usage of one samba process (not smbd). Memory usage builds up and takes around 4-5 days till it eats all memory (2GB RAM and 2GB swap) and then the server freeezes. Before it has enough memory, #service zentyal samba restart helps sometimes and sometimes helps only kill -9.

it looks like this in top:
 
Code: [Select]
PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
 2913 root      20   0 2305860 1,027g   3692 D   0,3 52,6 111:09.30 samba
..................

When I checked #lsof |grep 2913
I see many open pipes:
Code: [Select]
         ............
samba      2913                   root 1022w     FIFO                0,9       0t0    4045559 pipe
samba      2913                   root 1023w     FIFO                0,9       0t0    4045570 pipe
         ............

999 according to wc vs 8 in other samba process

I couldn't find any error in /var/log/samba/samba.log but these lines are occuring every minute:
Code: [Select]

And as you can see, problematic is just one process (pid 2913) rest of them are ok.

Zentyal is regularly updated and configuration is almost default, it is running zentyal 4.2.2 with samba --version: Version 4.3.4-Zentyal on Ubuntu 14.04.1 and kernel 3.19.0-65-generic
Code: [Select]
#cat /proc/version
Linux version 3.19.0-65-generic (buildd@lgw01-01) (gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3) ) #73~14.04.1-Ubuntu SMP Wed Jun 29 21:05:22 UTC 2016
We have more zentyal servers on different sites, set up similarly (just the companies are different) and we have problem just with this one. Right now we have to restart service every 3-4 days. Do you have any other solution or experience?

Directory and Authentication / Samba shared folders unavaiable
« on: November 24, 2015, 03:55:56 pm »
We have a problem on one Zentyal server with samba authentication and mapping user's primary group. I found out Zentyal developers was trying change sssd to winbind, but they revert it before releasing. Probably revert wasn't complete and winbind is now staring with smb process.

User can not connect to all shared folders (except home folders and sysvol) on lastest Zentyal Devel server (Ubuntu and Zentyal completely updated)

Whole problem is in winbind user's primary group lookup. All users has primary group "users" (gid 100) and not "domain users". I can see in smbstatus all connected users with primary group "users".

So user doesn't have any permission to access to /home/samba, because is not in domain users group.

Temporary fix is here, but after few hours all problems come back:
http://serverfault.com/questions/476086/samba-winbind-user-resolution

In old version (4.1) is all fine.

Please help, it's URGENT.
