Hi, I run the Lemmy instance over at https://compuverse.uk I seem to be getting spammed with literally thousands of incoming activity requests (primarily coming in from lemmy.world and lemmy.ml). (I measured about 1 new request ever 0.01 -> 0.02 seconds)

The error message in the Lemmy logs is very unhelpful, giving 0 detail about the actual error itself.

The UUIDs in the activities seem to be all unique, rather than duplicates. Does anybody have any idea what's going on and why there is such a large torrent of requests coming in?

This was so bad it essentially caused a DoS attack on my instance, and brought it down. I have had to move the PostgreSQL server onto a more powerful machine in order to keep up with the request rate!

Any help or advice is greatly appreciated :)

Thanks,

Cameron

Just curious: are all of the requests coming from same IP and user agent?
