Several times a day, my Nomadnet server is getting pinned to 100% CPU with dozens of Nomadnet child processes. After about 5 minutes or so, they disappear and everything calms down again. Nomadnet normally only runs at about 4-6% CPU. I don't see any spikes in disk or NIC activity, but maybe this is DDoS?

this also happens to me for whatever reason randomly, I have a feeling it's actually rnsd which nomadnet automatically starts up because I vaguely remember seeing that with `htop` but I'm not super confident about that

also post the interfaces you are using, cause I'm using i2p, backbone and then have public backbone and i2p interfaces, the problem could be one of those.

All TCP-based. 2 Backbone listeners and 4 clients.
