> While running a stress test against apollo-1.1-20120209.032648-24 (many concurrent TCP connections), the broker became unresponsive.
> It logged several times: java.lang.OutOfMemoryError: GC overhead limit exceeded
> It also logged other warnings, probably related:
> 2012-02-14 14:14:49,273 | WARN | handle failed | org.eclipse.jetty.io.nio | Apollo Task
> 2012-02-14 14:18:39,073 | WARN | Problem scavenging sessions | org.eclipse.jetty.server.session | HashSessionScavenger-0
> It could not be stopped either, I had to kill -9 it.
> What can be done to avoid these problems?
> FWIW, java has been started with -server -Xmx8192m -Xms4096m
