Every 15 minutes exactly, in whatever terminal window(s) I have connected to my server, I’m getting these system-wide broadcast message:

Broadcast message from systemd-journald@localhost (Sun 2026-02-15 00:45:00 PST):

The only thing I found online that’s kind of similar is this forum thread, but it doesn’t seem like this is an OOM issue. I could totally be wrong about that, but I have plenty of available physical RAM and swap. I have no idea where to even begin troubleshooting this, but any help would be greatly appreciated.

ETA: I’m not even sure if this is necessarily a bad thing that’s happening, but it definitely doesn’t look good, so I’d rather figure out what it is now before it bites me in the ass later

    You can also look at how many network sockets you have open and where they are connecting. netstat -an will give you a quick look. lsof can help you figure out what is using those ports.

      If you really need that many connections there are some tcp tunables you can do to help them be more efficient.

        I went to sleep last night after posting this and left a ssh connection open to see what it did in the morning when I woke up. And when I woke up and checked it out, I found that coincidentally it stopped doing the timer almost exactly as I went to sleep, yet I don’t think I was doing anything that would make that happen. I have no idea why it stopped, but it hasn’t started again either.
