I don’t think this is a bug, I think it’s just a limitation but it’s interesting nonetheless.
Basically if you use something that creates thousands of unique connections (say, a DHT crawler), you’ll eventually completely kill Glasswire’s service requiring deleting data / clean reinstall
There’s a few extra steps just because of the example program that’s being used.
Download and install Go from https://dl.google.com/go/go1.10.windows-amd64.msi
Compile p2pspider from a Powershell prompt by running
go get github.com/fanpei91/p2pspider
NOTE: the following step will download NSFW metadata - yes, metadata only
p2pspider.exe -p someport -d somepath (empty folder somewhere with ~200mb of free space, open UDP port)
Leave that running for about an hour (?) and glasswire will become unusable (try clicking on the usage page). I also managed to get a message coming up saying the service had crashed but I can’t reproduce it.
