Wow interesting, ill check this out. This used to do this, are you using the latest trunk and have allocated pretty much all your ram to red5 :D
Yes it seems the server is quite cpu/ram intensive im having to order 4GB of ram on the slave machines im going to be migrating red5 to because its currently on a standalone server right now. joseph wamicha wrote: > Hi, > > Preliminary results of the load test show red5 running out of memory > (errors > can be seen in URL below) when it publishes several live streams. > > The current load test sources version can be found here: > http://www.korandu.com/red5loadtests/red5loadtests.html > > I will continue to try and improve and refactor the load test code. > > Memory runs out before initiating play from the flash end.
