Are there any soft/hard limits on number of instances you can have in mrf_simple for reject/unlist?

Just wanted to check something after making some additions today. I was adding domains to the remove from federated timeline today. I usually add one at a time and then submit since I have forgotten in the past to submit.

It was working as expected, but then after I had added a few, it said a reboot was necessary. I hadn’t made any other changes, and was just adding domains - clicking Submit - checking for more domains in the timeline - adding domains - clicking Submit.

Is there some kind of soft/hard limit that can trigger a need for a restart?
