John,
Here's my understanding of what may be happening:
* pvclient has done a gather data information and is waiting to
receive that data
* pvserver0 has received this "gather data" request is asking all
satellites to gather data
* pvserver1 also received that "gather data" request but before is
starts processing it, pv1 needs to pass on the message to it's "child"
i.e process 3 (this is the fancy tree based message communication that
we are now using. So now, instead of the root node sending the message
to all processes one after the other, it uses a tree structure).
* pvserver2 I believe is happily waiting for the next message. It
already processed the "gather data" request, sent the response to the
root (although root has not processed that response yet) and now is
waiting for the next request.
* pvserver3 is the rogue. It's stuck in "Cancel", hence it won't
receive any messages other send to it. This cancel was not done as a
part of this gather data request but was done at the end of some
previous request. Thus it's not yet able to receive the "gather data"
request pvserver1 is trying to send, consequently freezing pvserver1.
Of course, this is just one possible explanation. I've attached a
patch. Can you please test if this overcomes the issue. If not, you
may also want to try by connecting the "Cancel" out all together. That
will at the least help us narrow down the problem.
