I am running some python project based on client/server framework. It is
something like rpclient/rpcserver. pyzmq is a very important part of this
project. Now we are running into some trouble because of some errors in pyzmq.
Please refer to the following error msg:Exception in thread Thread-1:
Traceback (most recent call last):

I am using Python3.7.9 (actually I tried python3.7.9 and. python3.11, the same
error msg) in windows 11, and pyzmq 25.1.1. The msg I am sending is really
small. No way it would blow the buffer. I am using PUB at server side and SUB
at client side (I always saw XPUB and XSUB in the zmq.constants. Could they
possibly be another choices). I saw flags have 3 different values (corret me if
I was wrong), NOWAIT, NOBLOCK, SNDMORE. I am not sure if the choice of flags
value could be the reason.
Any of your input would be highly appreciated. Thanks!
CZ.
