I've started to do a little testing with APR (very little) and seem to be
having some problems I modified the proxy example to use APR and it was
much All I did was replace NioSocketAcceptor and NioSocketConnector with
AprSocketAcceptor and AprSocketConnector. I then ran about 100 req/s with
it proxying for apache. I got a lot of exceptions and cpu usage spiked to
almost 100% and stayed there after the test run was complete. Most of the
exceptions looked like:
[17:54:21] AprIoProcessor-5 WARN [] [] [
org.apache.mina.example.proxy.ServerToProxyIoHandler] - [/127.0.0.1:80]
EXCEPTION, please implement
org.apache.mina.example.proxy.ServerToProxyIoHandler.exceptionCaught() for
proper handling:
java.io.IOException: Unknown error 4294897281 (code: 70015)

I'm wondering if anyone else has run into this type of problem or might have
an idea of what I might have done wrong.
My testing was done with:
Linux 2.6.22
JDK 1.6.0_03
APR 1.2.7
Mina 2.0 trunk
Thanks,
