[Red5] R: OUT of memory!

[Giusanny]

Ok thanks, but how works red5-highperf.sh?
It just set the JVM garbage collector?

So if I want to use it I have just to modify red5-highperf.sh like "-Xms256M
-Xmx512M -XX:MaxPermSize=128m ..."
and then run red5-highperf.sh and than red5.sh?
It's right?

P.S. I see that if I start a live stream and then let 10 client connect in
almost the same time, the server crashes (well doesn't crash but doesn't
allow any other connection even http connections)!
But if I let the client connect one per time it works for 150 and more
client...could be a problem with the queue?
Now I have rtmp.event_threads_queue=0 in the re5.properties.

Any ideas?

Thanks a lot!
Giuseppe

don't know if solves your prob but maybe you can set JVM garbage collector
options like:

-Xms256M -Xmx512M -XX:MaxPermSize=128m
