threads stuck at sun.nio.ch.EPollArrayWrapper.epollWait(Native Method)

Hi All,
At some point xnio thread starts to use 100% CPU and doesn't exit this state until application is restarted, I am not sure if there is a workaround or fix implemented. Can you please suggest a workaround/fix for the below issue? I attached threads from the thread dump and current Netty, JDK and OS version .

Netty Acceptor version 3.2.3.Final-r${buildNumber}
Java Runtime: Java(TM) SE Runtime Environment (build 1.6.0_27-b07)(32 bit)
OS-System: Linux 2.6.9-42.0.3.ELsmp,i386
