Hi,
I used the servicemix 3.3.2 with the component servicemix-
http-2011.01. now
there is one problem: when I concurrently send http requests to my
servicemix about 8/second, after some time, my servicemix could not
handle
any request.
I used j-console and found that there be some deadlock threads. one is
below:
