Re: [Red5] red5 uses 100% cpu

Well, I doubt if it's my app code because it is very simple and I just copied it from the oflademo as far as I recall. I've pasted it below if it's of interest.

Thanks,
Sean

The first link is an article from 2004 for jdk1.4 and tomcat 5.0; Red5 requires jdk1.5 and comes with tomcat 5.5.20 (latest stable). I have not see this 100% during any of my work with the server on two different PC's and an Apple. If this is an issue with Red5 then I would assume its in the MP3 handling code or your own application.

sorry Sean, I haven't seen this happen with the Red5/Java.exe.

However, based on you description, Chris Allen might have had a similar experience with the wedding Kiosk application

Chris, is this what was happening to you?
