Somewhere between the 5 minute mark and 0, everyone gets kicked from the server for packetflooding . Unfortunately, I can't find any supporing log file entries to post here. I will try to capture more info next restart.

Since this saves the server, that is entirely possible. If you have a lot of things saving at once, that can happen. That isn't really particularly related to this plugin, just happening due to the save process. The only things this does otherwise is send messages, which isn't any different than any other plugin that does the same.

Thank you.
