I hope wrong config option. It looks like we need 3 GB of memory while
only 1GB was configured.
Since config change looks more stable.

ConcurrentModificationException occurred after OOM. There was some
others as well. In addition
UDP listener was gone and probably clients as well:
java.nio.channels.ClosedChannelException
at
sun.nio.ch.DatagramChannelImpl.ensureOpen(DatagramChannelImpl.java:107)
at
sun.nio.ch.DatagramChannelImpl.send(DatagramChannelImpl.java:216)
at
com.sun.grizzly.util.OutputWriter.flushChannel(OutputWriter.java:295)
at
com.sun.grizzly.util.OutputWriter.flushChannel(OutputWriter.java:256)
But OOM was the first one.

Tigran.
