I've been seeing an issue where Cygwin commands sometimes take a while to
complete, or they will not complete at all and will have to be manually killed
through task manager. I installed Cygserver and that helped to lessen the
number of times that the issue happens but it didn't get rid of it. I'm
wondering if anyone has run into the same behavior. I've also shared the .dmp
files of a 'cp' command that was taking a while to complete in case that helps:
cp.dmp
