   Message for #Pixelfed admins

   Do any of you encounter the following? Every 6 hours and consistently, my pixelfed server goes into a high memory usage, process is php-fpm triggered by pixelfed, before being killed by oom. Clearly a bot, never happened before.

   Now I changed server with a full fresh install and new IP but it still goes on (even changed OS from 22.04 to 24.04, bumped RAM from 16 to 32 GB and php8.3 version to 8.4).

   Do you administrators see similar behavior? See attached Grafana/Prometheus dashboard for illustration on a 24-hours period.

   Any clue on how to mitigate such DoS attacks?
