java.net.SocketException: Cannot allocate memory

[Brian Call]

Hi Guys,

I'm seeing an ugly issue crop up on JDK7 for MacOS that I'm at a total loss to diagnose or even begin to fix. At random times (and sometimes every time) I'm seeing this exception:

Caused by: java.net.SocketException: Cannot allocate memory
	at sun.nio.ch.Net.joinOrDrop4(Native Method)
	at sun.nio.ch.Net.join4(Net.java:421)
	at sun.nio.ch.DatagramChannelImpl.innerJoin(DatagramChannelImpl.java:848)
	at sun.nio.ch.DatagramChannelImpl.join(DatagramChannelImpl.java:866)
	at org.jboss.netty.channel.socket.nio.NioDatagramChannel.joinGroup(NioDatagramChannel.java:158)
	at org.jboss.netty.channel.socket.nio.NioDatagramChannel.joinGroup(NioDatagramChannel.java:135)
	at com.soterawireless.h1s.groups.NioGroupSubscriber.joinGroup(NioGroupSubscriber.java:203)
	... 5 more

This same codes works great on both Linux and Windows but fails intermittently on Mac OS 10.8.x. Google is letting me down and stackoverflow isn't being very helpful either...

Does anyone have any insight on what might be causing this join group call to fail in such a manner? I could very easily write a simple test driver to demonstrate the problem so please let me know if that would be helpful. 

Many thanks in advance! 

Blessings,
