| whenever EJB3 client requests the Server new socket is being created. at
the client side the socket connection pool is not being used. Hope there is
some issue with the socket connection after getting response from the
server,becoz of which the server side the connection is being closed. this
increases the CPU utilization,

| The same code is running fine in jboss 4.0.4 with jboss remoting 1.4.0
|
| new remoting 2.2.2 SP4 only handling 1/4 of the load with high CPU
utilization.

| This is keep on happening.....
|
|
| also i have seen in the netstat -nac | grep 3873
|
| in this i am able to see the client side port is changing and it is
increasing for each connections made
|
|
| I am using default configuration of ejb3 remoting conf
|
|
| jboss.aop:service=AspectDeployer
| socket://${jboss.bind.address}:3873
|
|
| org.jboss.aspects.remoting.AOPRemotingInvocationHandler
|
|
|
|
| Is there is any other configration change i need to make it with the
current release so that the problem i am having will get resolved...
|
| One thing i am not able to understand is y the connection getting closed
for each call at the server side, this closing needs to happen only after the
timeout.
| i Hope there is some exception which causes the connection to close
forcely...
|
Kumarselvan, after a worker thread
[org.jboss.remoting.transport.socket.ServerThread] processes an invocation, it
should just go to the top of a loop and wait for the next invocation. If the
load is very high, the server will try to close a ServerThread's socket and
reuse it with another socket, but I wouldn't expect the regular behavior you're
seeing. Another possibility is that some exception is being thrown in the
course of handling an invocation, which would cause the socket to be closed.
Could you turn on trace logging so we can get more information? Add
| <category name="org.jboss.remoting">
| <priority value="TRACE"/>
| </category>
|
to jboss-log4j.xml in the conf directory. See
http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfigureLogging for a discussion of
logging in the Application Server. Thanks.
