I am not sure about your VM settings.

from my point of view if you have:
-XX:+UseConcMarkSweepGC

together with the other params, then there should be some kind of Exception
on startup / startup fails.
The default params in the red5-highperf.sh are not correct, at least for the
Java6 JRE.
So I wonder how you can use this param combination without a fail on
startup.
