samba - May 2019 - Upgrade from 4.9.8 to 4.10.3 on Centos using Sernet Packages

In addition to Rowland comment. 

if you still able to test it. Remove 1 setting at a time, restart and test it. 

Start with these, in this order. 
        logging = syslog only		
        prefork children = 8

I think if the logging line is removed your problem is solved.
man smb.conf /logging should explain more. 

Because I cant/find the setting :  logging = syslog only



Greetz, 

Louis

Hi Louis,
as for the prefork option. With this on the error at least tell what
process crashed:


May 20 10:41:32 dc3 samba[6452]: [2019/05/20 10:41:32.087878,  0]
../../source4/smbd/process_prefork.c:519(prefork_child_pipe_handler)
May 20 10:41:32 dc3 samba[6452]:  prefork_child_pipe_handler: Parent
6452, Child 6712 terminated with signal 6
May 20 10:41:32 dc3 samba[6452]: [2019/05/20 10:41:32.088265,  0]
../../source4/smbd/process_prefork.c:463(prefork_restart)
May 20 10:41:32 dc3 samba[6452]:  prefork_restart: Restarting [ldap]
pre-fork worker(7)


So a ldap process crashed.

Hai, 

A few more questions.. 

Is this a 32bit system or 64bit system? 
What is the used ldb version? ( should be 1.5.4 )

I dont know RH, so i want to see the installed packages, with this egrep. 
egrep "ldb|tdb|tevent|samba|winbind|talloc|lmdb|talloc|wrapper"
A version running 4.9.8 and a 4.10.3 would be great to see for me. 

It could be related to lmdb, bre these DC's provisioned with backend (l)mdb
backend.

And you upgraded from 4.9.8, which steps did you take before and after that
upgrade.

Greetz, 

Louis

as the sernet packages provide everything needed this line will not
provide useful info.

libtdb 1.3.18
libtalloc 2.1.16
libtevent 0.9.39
libldb 1.5.4

are in sernet-samba-libs. The rest I haven't found yet.

The domoin was classic upgraded with Samba 4.4. First with two DCs then
later two more where added. I only tried the upgrade with one to test
it. All upgrades where done in place. So no leaving the domain and
joining again.

I did dbcheck (everything ok) stopped samba-ad. Upgraded. rebooted the
server. Tested dns update, Check repl, dbcheck etc all fine. After some
minutes I see the crash in the logs. Stopped the server and reverted
back to the snapshot. Tested if all is fine (dns update, Check repl,
dbcheck).

Hello Cristian, 

Well, nothing to say about your steps, these looks good. 
And lmdb could be disable in the sernet packages, cant say, i dont know. 

And only one DC has these problems or all? If only one DC crashed. 
Which DC crashes. Last added? Oldest? 


Greetz, 

Louis
