I have switched to using htpasswd authentication.
I am using xmlblaster 1.2 (because 1.3 dies in doSend, see other message)
I am using the socket protocol.
when a connect Qos is received that doesn't properly validate, the connect "call" fails (as expected), however xmlblaster doesn't close the tcp socket.

Hi Brad,

this is a ugly leak.

How can i reproduce it?

I have tried profiling (with http://www.khelekore.org/jmp/)

 java -Xrunjmp:nomethods,dumpdir=/tmp/jmpdump/ org.xmlBlaster.Main

and a client with invalid authentication (with activated htpasswd):

java javaclients.HelloWorldPublish -session.name joe/2 -Security.Client.DefaultPlugin "htpasswd,1.0"

but i can't reproduce any leak (i've also checked with lsof -i).
I'm using the current xmlBlaster svn.

Please provide more details to track this down,

thanks
Marcel

the client reconnects (I guess it's not closing the socket either), and eventually xmlblaster runs out of file descriptors..

Here's a partial output from lsof
