fusion 8.5.0 on sierra
guest ubuntu 16.04 amd64
for the last few versions ive been piping data over ssh, which has worked reliably until now. now, when i try it, it not only hangs and times out, it also freezes out incoming ssh connections for a random time, sometimes until rebooting the guest. during the freeze, all other network traffic works fine. even ssh within the vm, to itself or to nested kvm instances, work fine. this happens randomly, but more often than not. rebooting the host or vm doesnt seem to help.
ssh to other vms, that i dont pipe to, is still reliable.
