[Samba] replication fails after internal error 11 / panic

Hi,

We have three DC's, and one of them has been misbehaving a few times 
lately, stopping to replicate, showing the following error in samba-tool 
drs showrepl, for all DC partitions:
> DC=DomainDnsZones,DC=samba,DC=company,DC=com
> 	Default-First-Site-Name\DC2 via RPC
> 		DSA object GUID: 5e93a102-2963-496a-af16-0c51eebb2e31
> 		Last attempt @ Wed Nov 11 06:41:21 2015 CET failed, result 121
(WERR_SEM_TIMEOUT)
> 		4 consecutive failure(s).
> 		Last success @ Wed Nov 11 06:24:34 2015 CET
Similar behaviour for this DC2 has also been observed when this DC2 was 
still on 4.1.17-sernet. I upgraded to 4.2.5-sernet, hoping that this 
would perhaps solve the issue.


I have a loglevel 3 log from that DC2, and it shows the following:

This DC2 has only been running very short, after a scheduled reboot for 
backup:

[Samba] replication fails after internal error 11 / panic

Hai MJ,  ( gelukkig nieuwjaar he ..  ;-) )

First, why sernet 4.2.5 current is 4.2.7 Upgrade to 4.2.7 first i suggest. 

And : Last attempt @ Wed Nov 11  <=  11 Nov ? latest really? 

The "misbehaving server" check the time first. 

Try to run : 
knit Administrator
samba-tool drs replicate <destinationDC> <sourceDC> --full-sync -k 

reboot your server, check time, check logs. 

Ow and for you to know. You mail A/MX are wrong for list. 
<lists at merit.unu.edu>: host    
postoffice.merit.unu.edu[2001:610:1208:6:192:87:143:1] said: 550 No RDNS
    entry for 2002:c386:ad78::1 (in reply to RCPT TO command)

2002:c386:ad78::1 should resolve back to ipv4. My server does not have a
"real ipv6" number

If you are going to upgrade, I would suggest that you investigate 
compiling Samba yourself, the 4.1.x series gets security fixes only at 
the moment. The 4.4.x series is slated for release on the 8th March, at 
this time, 4.1.x will go EOL, 4.2.x will move to security fixes only, 
4.3.x will move to maintenance mode.

I thought the same as Louis, why wait nearly two months to report a 
problem, unless he hasn't waited two months and time is badly wrong on 
the DC.
