[Samba] CTDB upgrade to SAMBA 4.8.3

[Micha Ballmann]

Hello,

i upgraded my ctdb cluster (3 nodes) from samba 4.7.7 to 4.8.3. Followed 
the steps under "policy" in this wikipage 
https://wiki.samba.org/index.php/Upgrading_a_CTDB_cluster. I shutdown 
all CTDB nodes and upgraded them. After the upgrade i started all nodes 
and ctdb status shows:

Number of nodes:3
pnn:0 192.168.199.52   OK (THIS NODE)
pnn:1 192.168.199.53   OK
pnn:2 192.168.199.49   OK
Generation:1484961991
Size:3
hash:0 lmaster:0
hash:1 lmaster:1
hash:2 lmaster:2
Recovery mode:NORMAL (0)
Recovery master:0

Now i have the problem that "testparm" outputs, for me not readable 
informations:

root at ctdb1:~/ctdb# testparm
Load smb config files from /usr/local/samba/etc/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)

Abgebrochen (Speicherabzug geschrieben)

But im able to add new parameters like "net conf import smb.reg" and 
"net conf list" shows me the right output.

BY THE WAY, THE CLUSTER IS WORKING! How can i fix the testparm issue or 
what did i wrong?

Thanks again!
