[zeromq-dev] ZMQ Freezing Windows

Dave, I have experienced the freezing problem you describe with Windows 7. I am using the NUGET package in a Windows service project built with VS 2010. It may freeze with no keyboard and mouse control  and you must perform a power button shutdown. Alternatively it may slow down the UI greatly, when this happens task manager will reveal that the process 'ekrn.exe' (this is ESET) is taking 50% of cpu resources, but Windows behaves like it is taking 99%. I found this post that pointed me in the direction of antivirus, ESET in my case.


If you are using ESET antivirus or some other antivirus make an exception for your executable. In ESET it is found under Advanced setup > Antivirus and antispyware > Exclusions. Add the path to your executable.

I've been trying to write a broker using ZMQ and found that it would
occasionally lock my PC totally, requiring a power-off as the usual
Ctrl-Alt-Del etc, and even a shutdown request by pressing the power button
did nothing.
