|Hi,
|
|I've just had another long debugging session,
|and I think I'm onto something...
|
|Using packet sniffing on the loopback interface
|I discovered that the hanging client has sent a
|request to the jBoss webserver at port 8083, but
|not received a reply. In fact jBoss didn't even
|read the request - it remained stored in OS kernel
|buffers.
|After some more debugging I discovered that the
|webserver had not even done an accept() for the
|connection that the client already had sent a
|http request on.
|Looks like the Java VM on Linux does the accept()
|syscall long before accept() on the serversocket!
|
|So why does the webserver never accept() the
|connection?
|Looks like no thread for doing the accept().
|When debugging the webserver threadpool, I have
|discovered a problem that can end up in a situation
|where the same thread is entered multible times in
|the stack of idle threads.
|A quick-and-dirty fix seems to make the client hang
|go away.
|
|With a bit of luck I'll be ready to commit a fix
|for this today or tomorrow.
|
|
|Best Regards,
|
|Ole Husgaard.
