3:34 p.m.
I tried to post this earlier but didn't see it show up. I apologize if it gets posted
twice.
I'm not exactly new to JBoss but I've never dug down very deep into it. I've
looked around and haven't been able to answer my question so any help would
beappreciated.
I'm running some tests with my application in JBoss using httpClient 3.0.1 to send the
URLs to Apache 2.2.6, which routes them to JBoss 4.2.2GA. Java release is 1.5.0.10. My
client machine is running Linux 2.6.15.4 Fedora Core 3. The server running JBoss is
running Linux 2.6.18-1.2869.fc6. I am running my testin Eclipse 3.1.0.
My test client is getting about 10% errors. Most of them are java.net.ConnectException:
Connection refused but some are java.net.SocketException: Connection reset. When I look in
the JBoss log I see it's getting some ClientAbortException: java.net.SocketException:
Broken pipe.
Obviously JBoss is listening on the port and performs most of the requests. I am not
hitting the server all that hard. My test client will see this happen when it sends a
request every 5 seconds. The requests involve uploading a file. Maximum threads I'm
allowing for JBoss is 200 and its only using around 18. I think Apache has around 200 but
I'm not sure.
It looks like the server thinks the client is closing the connection at times. Looks like
the client is getting the connection reset by the server (connection reset), and the
server is not listening sometimes (connection refused).
If anyone has any ideas that I should try please let me know. Thanks in advance.
Server and client stack traces follow.
This is the stack trace from the JBoss server log:
