yarnd filled up the disk on the VPS where I run it. It's never done anything like this before and I have no idea why it would start. But it threw almost 700 Gbytes of data into /tmp in files like this:

164 files. Some are empty, some are 7 or even 10 Gbyte.
Any idea what would cause that? And why now, after running
yarnd for so long with nothing like this happening?

I'm going to have to shut down my server soon. This looks like some kind of DDoS. Whether intentional or not it's filling up the disk at an unsustainable rate.
