I wrote a short article about the server migration:
@trashserver Check the server for IoT bots.
If you talk about the statistics of memory used on your server, uninvited guests are hooked.Bots send 10 messages per second, so this is a very high load on Prosody
@mike @trashserver almost - we are 1 test short, see https://compliance.conversations.im/server/tigase.im/
The thing missing are avatars in MUC rooms (specific subset of XEP-0153: vCard-Based Avatar, which is supported in itself)
Upcoming 8.1.0 will have 100% :-)
@trashserver glad I spotted this, I've been considering doing the same thing myself.
One of the first Mastodon instances, there is no specific topic we're into, just enjoy your time!
