Description

In high load situations, with a NO_ACKNOWLEDGE session, it is possible for the client to create an excessive amount of threads to suspend/resume the channel.
I'm providing a patch to avoid creating a new thread if the previous thread has not completed its operation. This patch appears to avoid the problem in our environment. Notice we are using version 0.24, but the code is the same in the latest version.
