[Samba] Samba 4.1.5 memory consumption - again

[Łukasz Tomaszewski]

Hi all,
At the pre-big thanks to the SAMBA team for many years the great work.

Sorry for my english.

A week ago, have implemented productively Samba 4.1.5 on CentOS 6.5. I
installed samba by default dns server built-in (internal) with the rfc2307.
Everything works great, but after a while I noticed that the memory on my
server is largely occupied.

At this time there are about 10 users domain - that samba should be bored,
but it is not.
Installed clean system. No other processes devouring memory.
Is 12GB of RAM is not enough for samba?

Does anybody know what can be done? Is this normal? How can I check what
these huge processes do?

Thanks everyone.
