Based on both your suggestions, I stopped a resource-intensive job that was running, and also "reniced" Tor to give it priority. Since then, I haven't encountered more "resource unresponsive" warnings.
Thanks for your help!

I keep getting NYX_NOTICEs about "Relay unresponsive". They happen every few hours, and last for minutes or sometimes a couple of hours before I get a "relay resumed" message.
As Damian Johnson has said, it is hard to guess the cause without more clues. But keep in mind that 2MB/s with 7k connections puts a considerable load on the operating system. Are you sure it’s not your machine that is limiting performance of your relay? That could cause temporary, short lockups, preventing nyx from receiving notifications from the relay in time and considering it unresponsive.
That’s my guess after seeing that your average traffic hovers under 200kB/s. This alone does not indicate any problems with your configuration yet, because it’s also a matter of how much connections you actually receive. But together with the “Relay unresponsive” warning it reminds me of what I see when my own node is experiencing hiccups during high load from other sources.
