hi charlie i’ve changed my server to take a dedicated one for wowza, and i re installed wowza on the new server. Java install was ok, java -version gives me the correct path and version, but when starting the server here is what i have: Configure logging: file:///usr/local/WowzaMediaServerPro/conf/log4j.properties INFO server server-start Wowza Media Server Pro10 1.3.1 build4415 - INFO server comment - Serial number: XXXXX-XXXXX-XXXXX-XXXXX-EEDNX INFO server comment - Maximum connections: 10 INFO server comment - Hardware Available Processors: 2 INFO server comment - Max File Descriptor Count: 1024 INFO server comment - Open File Descriptor Count: 30 INFO server comment - OS Name: Linux INFO server comment - OS version: 2.6.21.5-grsec-xxxx-grs-ipv4-32 INFO server comment - OS architecture: i386 INFO server comment - Java vendor: Sun Microsystems Inc.

I have never seen this problem before. I just found this web page that describes this problem: [http://www.rogue-development.com/blog/labels/red5.html](http://www.rogue-development.com/blog/labels/red5.html) It is suggesting that you add the Java swith: -Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.PollSelectorProvider To the Wowza Pro startup. To do this edit the following two files and add this qualifier to the JAVA\_OPTS value near the top of the file: /usr/local/WowzaMediaServerPro/bin/setenv.sh Please let me know right away if this does not work for you and I will dig in.

Great! I will add this to the README.html, bugs and useful code sections on the forums. Charlie ---

just to make sure, my line should look like this: JAVA\_OPTS="-Xmx768M -Djava.nio.channels.spi.SelectorProvider=sun.nio.ch .PollSelectorProvider" thx ---
