Hi Lars,
thanks for providing the test case. However we've some loadtests as
well and they have a similar setup without using a foreign client
library like your test and they all work fine. For instance
"WebSocketLoadD13Test.java" in jetty8.
If you can provide a test without using a foreign library and using
jetty's api only, then we'll do some further investigations. Until
then we presume that the issue is in the library you use as we've
working load tests for jetty and cometd.
Cheers,
Thomas

Hello,
Here's a strange behavior I'm looking at: Sending more than 3
quick consecutive messages to a WebSocketServlet fails silently,
it looks as if the messages are dropped. The 4th and onward
messages never seem to reach the web socket. This can be
reproduced consistently on my environment.
I'm attaching a unit test case which demonstrates the problem.
Playing around, it seems that it is the SelectChannelConnector
that somehow screws it up, using the old SocketConnector works. It
also appears to be a timing-realted issue, adding a
Thread.sleep(X) between the messages makes it work.
The attached Maven project uses the Weberknecht client libraries
to connect to the server. Those aren't in any repository as far as
I know, but you can download them here: http://code.google.com/p/weberknecht/.
My appologies for the inconvenience.
I assume this can be related to: https://bugs.eclipse.org/bugs/show_bug.cgi?id=357318
My environment is:
Linux 2.6 x86_64 (Mandriva)
Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)
Also attached is a thread dump when the test was waiting for
messages to echo back. It looks normal to my eyes, but I'm no
Jetty expert.
What do you guys think?
