Problem
When I attempt to start Wowza Pro on Linux I get an error message that looks like this:
Error starting: java.lang.reflect.InvocationTargetException

This is a know issue with certain versions of the Linux kernel.
Solution
To fix this problem, edit the following two files:
/usr/local/WowzaMediaServerPro/bin/setenv.sh
and change the following line in both files:
from:
JAVA_OPTS="-Xmx768M"
to:
JAVA_OPTS="-Xmx768M -Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.PollSelectorProvider"
