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

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

I only upgraded one. Not the oldest and not the newest. To test the upgrade. 3
our of the 4 are VMs. This one I usually test upgrades with (until now I never
had to revert). It is the only one that is just a DC. The others have either
radius or dhcpd running. I haven‘t tried the others yet.

Hello you all,
I did some more tests used Samba 4.10.4 and still the same Problem. I
also upgraded all the DCs and the problem is the same on all of them.
Downgraded all of the an problem is gone.

I went up to loglevel 5 an saw nothing that was related. How do I debug
further?

@rowland: I wrote to bugzilla-maintenance at samba.org to get an bugzilla
account but haven't gotten any feedback. What else can I do?


Regards

Christian
