Hi all,
I get a connection "Read timed out" exception after a while. I'm testing
using a modified version of a Java example (that just runs in a loop 5000
times: send 1 msg, sleep) running on Linux (connecting via localhost to the
0.5 c++ broker). I'm using the java client libs from the 0.6 tree (though
it happens with 0.5 as well).
After a while, a mysterious read time out appears. Here's the error:

------------------
there appears to be nothing in the broker log file except the recorded
disconnect:
2010-feb-09 18:11:11 debug DISCONNECTED [127.0.0.1:58825]
2010-feb-09 18:11:11 debug [email protected]:
detached on broker.
I've attached my sample code, configuration file, and the output from the
client trace (client.log) and the broker (qpidd.log).
NOTE: this happens even when connecting to a broker outside of localhost.
HOWEVER: if I run this program on an external machine and sends messages to
the broker, there is no timeout exception. It also works fine with a
similar python test (loop and send 1 msg). I think, therefore, the problem
is in the client lib (not the broker).
I'm using a linux VM with java version "1.6.0_18", if that is helpful.
Any advice on troubleshooting this would be appreciated.
