hdbaddhost - Master name server not responding

HI all,

Anyone seen this error before when adding a node to an existing scale-out system?

[40739]{-1}[-1/-1] 2016-04-14 10:01:21.651061 e TNS TNSClient.cpp(00800) : sendRequest setstarting to hananode5:30501 failed with NetException. data=(S)databaseid=2|host=hananode6|port=30503|(I)type=1|(B)watchdog=0|(N)node=host/hananode6/indexserver/30503|...|

[40739]{-1}[-1/-1] 2016-04-14 10:01:21.651077 e NameServer TREXNameServer.cpp(09847) : master nameserver@hananode5:30501 not respondin.g retry in 5 sec

Telnetting to hananode5 on port 30501 works fine as well as a telnet from node 5 to 6 on port 30503.

Regards,

Sander
