Wordpress (developer) gets stuck (health check + Activity Pub plugin?)

[David 0]

Hey,

I've noticed that for a few weeks, my Wordpress (Developer) gets stuck every once in a while.

The logs point me at either the health check, or assumedly the Activity Pub Plugin, this occurs more often that it should, I guess:

For now, I have deactivated the AP plugin and will observe. The app itself should have sufficient RAM (4GB) and CPU (75% of 4 cores) assigned.

@David-0 did you get this sorted out?

At least, since I deactivated the plugin, this issue did not occur again. I missed looking up, which users from those mentioned Mastodon servers followed my blog. Maybe their account was closed, creating some error?

@David-0 possibly, but might also be some plugin issue. I guess https://wordpress.org/plugins/activitypub/ is the plugin right?

Right, the one by Matthias Pfefferle and Automattic. It enables your blog as fediverse-instance and allows users, e.g. on mastodon to follow your blog. They can even reply to "posts" in their timelines, and those replies appear as comments on the WP site.
