You can add me to the list.

My environment: CentOS 4.7 x86_64, jdk-1.6.0_07, php-5.2.6, httpd-2.0.52-41, mysql-5.0.67-1, Dolphin 6.1.4, and RMS 3.5.1. I even tried compiling my own version ffmpeg and also the latest SVN version of the red5 server. I get the same thrown java exception:

[ERROR] 2008-09-23 10:28:20,919 pool-3-thread-7:( org.red5.server.messaging.InMemoryPushPushPipe.pushMessage ) exception when pushing message to consumer

Sorry I don't have a solution, but at least you know see more you are not alone. Either something is broken, or we are all doing something wrong.
