[Samba] Samba Version 4.1.9-Zentyal (Zentyal4.0) is using a lot of RAM memory to crash
I have been using two Zentyal 4.0 domain controllers for a long time.
3Gb of RAM each one and working okay. I have not updated them from
Internet and my users are the same. Suddently, the first DC began to
comsume memory to the top.
I detected that samba processes are the responseble of this behavior.
More processes with more memory come on. They get more and more memory
in such a way that the server crash in one day. If I add more memory
size (5Gb) to this
virtual machine it crash anyway when it reach that new size.
I have two possible solution:
1- To find a fix
A lot of solutions are related with upgrade the samba and the
kernel version but no thing about
change a configuration, or something like that.
2- To replace the domain controllers with new ones (Version
4.3.11-Ubuntu, Ubuntu 16.04). Because It should be difficult
to upgrade the current ones (They are too old versions).
Following this way, I demoted the 2nd Zentyal and tried to add the
Ubuntu 16.04 as a second domain controller using
the primary Zentyal as controller, but It got this error in the
replication process and can not join to the domain:
===================================================================
Replicating critical objects from the base DN of the domain

How to fix this specific replication problem ? Or how to keep the
Zentyal 4.0 from getting more memory resources?
Thanks in advance!
