2294113 - Diagnostics Agents do not communicate with SAP Solution Manager 7.10 due to IPV6 usage

Symptom

The Diagnostics Agents (SMDAgent) connect to the SAP Solution Manager because the IPV6 protocol is used. In the SMDSystem.log the following error is shown:

Mar 14, 2016 4:06:34 AM [Thread[Connector,5,main] ] Warning Connecting to SMD server ms://solman.host.com:8101/P4 failed - error counter: 10935 - com.sap.engine.services.jndi.persistent.exceptions.NamingException: Exception while trying to get InitialContext. [Root exception is java.io.IOException: Can't get Socket. Reason:Network is unreachable: connect (port 8101 to address ::ffff:10.120.120.120)]

The address highlighted above indicates that IPV6 protocol is being used.

This issue could affect other agent applications, like the DPC push(dpc.log):
