APR

[Geoff Cadien <gc...@gmail.com>]

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:

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,
