--------------------------------------------------------------
Hi all!
I'm seeing this error also, and don't know how to get over it. I am using JBoss AS
5.1.0.GA with jboss-remoting 2.5.1, and also checked with jboss-remoting.jar 2.5.4.SP3 in
client and common/lib folders (not sure if I should replace more JARs)
These are the tests that I have done so far:
1. Nessus scan on port 3873

Don't know if this was solved by the original poster somehow, but if someone has a
clue where to keep looking, I'd be much obliged!

Is jboss hanging as in the original post or are you just seeing these errors in the logs?

The server is not exactly hanging, since I can access local EJBs, and also access
databases and so on. The problem is it looses all ability to invoke remote EJBs and
viceversa. We have several AS deployed, and we've seen this behaviour in two machines.
Any clues?

I have not seen this before, where it looses the ability to invoke EJBs.
You are saying the jboss instance cannot invoke other EJB's from a different machine
(likely running jboss also?) and clients are unable to remotely invoke EJBs on that jboss
server that is having the problem after the Nessus scan?
What are the errors you're seeing when the jboss server is unable to invoke a remote
EJB running on another (jboss?) machine?
What error do you see on the client side when it is unable to invoke EJBs running on the
jboss instance that is having problems?

Sorry, it was a typo on my side: it is Nagios, not nessus, what we use to monitor status
of AS.
We have the following setup:
* Several AS, each one in a different server.
* EAR deployed in each AS. Every app is the same (i.e. the same EAR copied in the deploy
folder), and some parameters like address and some ids are configured to identify each app
deployed in one AS from another. This application has a local EJB layer to serve
information to a GUI, and a remote EJB to allow exchange of information between different
applciations via EJB-RMI in ports 1098-1099-3873.
Everything went well untill we started monitoring with Nagios on these ports, and
we've discovered that it is port 3873 (EJB3 Remoting Connector) the one causing
problems by doing these direct telnets. After some time, two of the AS stop sending or
receiving information from other applications. We've been debugging, and the
appliation can work normally with local EJBs and so on, accessing DBs, JMS queues... but
when we get to send something, it hangs doing the context.lookup of the remote EJB.
We are stucked at that point, trying to figure out what it is. Could it be that the
connections stablished by Nagios are not closed correctly and the AS runs out of
connections?

Can you get a stack trace of the threads that are hanging when they are hanging?
Unix : kill -QUIT <jboss-pid>
Windows : CTRL+BREAK in DOS window (if any)
jmx-console (jboss 5 or 6) : "jboss.system" -> "type=ServerInfo"
-> click on button for "listThreadDump"
JDK jstack : jstack [-F] -l <pid>
You could also try jconsole, jvisualvm or MBean java.lang.Threading
("java.lant:type=Threading") "dumpAllThreads()".
That might give a bit more insight as to what is going on here.

Sorry for the late reply. We've stopped monitoring those ports with Nagios, and the
problem disappeared. I will try to set a test environment in a virtual machine to try and
reproduce the problem, but I won't have it at least before a week, since we are quite
busy at the moment. I will also try to reproduce the problem in a JBoss installed in my
development machine. I tryed doing telnet to a local JBoss and the problem is the same,
but I need another one running in a VM to see if they can communicate.
Let's see if we can nail this down, 'cos now I'm really curious to find out
what is happening!
I'll write back when I have more info on the matter.

Hi,
We are facing similar issue, could some one help to resolve this issue?
it is happening due to scans performed.
Thanks
