[Samba] Samba-4.1.18 romaing profile causes memory leak

[hy wu]

Hi List,

I used samba-4.1.18 as domain controller and tried to use romaing profile.

I got memory leak when every account with profile path setting logout.

Every account with profile path setting eat almost 10mB memory so my samba
machine crash if there are many hundred account with profile setting in
domain.

Any option in smb.conf or operation can help ?

This is my reproduce setps:
1. create domain "testdom.ork"
2. create 10 accounts and set profile path in "share"
    for example : profile path of "user1 " is "\\dc.testdom.ork\share\user1"
3. check MemFree in /proc/meminfo
4. login/logout 10 accounts created in step 2
5. check MemFree in proc/meminfo   <---almost 100mB reduced

my smb.conf:

[global]
workgroup = TESTDOM
realm = TESTDOM.ORK
netbios name = DC
server role = active directory domain controller
dns forwarder = 127.0.1.1

[netlogon]
path = /usr/local/samba/var/locks/sysvol/testdom.ork/scripts
read only = No

[sysvol]
path = /usr/local/samba/var/locks/sysvol
read only = No
[share]
path = /share
        read only = No
