Gemfire problem

I have a problem with 2-node cluster installation of Livececle ES 8.2 Update 1.

After installing and configuring both jboss servers i get following errors on whichever server that is started second.

First error is allways (from server.log):

at  com.adobe.livecycle.cache.adapter.CacheAdapterFactory.getCache(CacheAdapterFactory.java:102)

...

with

Caused by:  com.gemstone.gemfire.SystemConnectException: Received no connection  acknowledgments from any of the 1 senior cache members: NODE1:2359/2356

These errors then repeat several times causing failed deployment for umcache.war and consequently failed deployment for livecycle core.
My gemfire.log shows:

It seems that nodes are able to find each other via UDP multicast but node that is started first doesn't reply (in 15 seconds) to startup message sent by second node.
If i start one server with different multicast port (–Dadobe.multicast-port) so that nodes cannot see each other then both servers start without errors.
I followed all instructions for cluster deployment and installation to best of my knowledge but this error keeps appearing.
Please help.
Thanks

Can you send the complete server.log files from both cluster members to dev_info@adobe.com?  Also, please send the Gemfire.log file from \LC_TEMP\<your_server_name>\Caching\ of both nodes.

Thanks.

Using TCP locators instead of UDP for cluster caching resolved this issue.

Can anyone suggest how to implement the TCP locators on Windows to start automatically, rather than manually calling the start and stop locators

Adobe does not test or provide a specific solution, leaving this up to the customer. Some customers have used the Java Services Wrapper to handle and manage running the TCP Locator as a windows service. http://wrapper.tanukisoftware.com/doc/english/download.jsp
