I am interested in if you changed any memory settings to accomodate
those 400 users. I am looking to stream pre-recorded flv videos to
(hopefully) a large number of people. I received a Java out of memory
error though:
[java] Exception in thread "FlowControlService"
java.lang.OutOfMemoryError: Java heap space
[java] Exception in thread "DefaultQuartzScheduler_Worker-3"
java.lang.OutOfMemoryError : Java heap space
[java] Exception in thread "DefaultQuartzScheduler_Worker-9"
java.lang.OutOfMemoryError: Java heap space
[java] Exception in thread "DefaultQuartzScheduler_Worker-4"
java.lang.OutOfMemoryError: Java heap space
[java] Exception in thread
"DefaultQuartzScheduler_QuartzSchedulerThread"
java.lang.OutOfMemoryError: Java heap space
[java] Exception in thread "SocketAcceptor-0"
java.lang.OutOfMemoryError: Java heap space
I am running red5-0.5 on Gentoo Linux with:
[echo] java.home is /usr/local/jdk1.5.0_07/jre and the target version is 1.5
I have now added "-Xms256 -Xmx1536" to red5.sh. I crashed, but just
after more load:
[java] Exception in thread "FlowControlService"
java.lang.OutOfMemoryError: Java heap space
[java] Exception in thread
"DefaultQuartzScheduler_QuartzSchedulerThread"
java.lang.OutOfMemoryError: Java heap space
In this case, my videos seemed to keep playing, they just stuttered and
stopped a lot. Does anyone have any tips here? My videos are currently
300k, but I'm looking to do 700k in the future as well. Would the
pre-.6 code work better?
The OutOfMemory exception is thrown because we are using memory mapped io for FLV reader and we don't use any sharing mechanism and cache right now. This should be fixed in 0.6 of course.
Thanks,
