There was an issue that affected a couple of Mastodon instances hosted on Masto.host where federation stopped working.
I am going to install a patch to try and avoid it happening again. It will require a restart but there shouldn't be more than 20 seconds of downtime.
I believe the issue is the similar to https://github.com/tootsuite/mastodon/issues/9362 but caused by the code introduced on v3.5.2 related to the new audio upload.
@mastohost Clearly the answer is more cocaine.
@joshuanozzi you can't imagine the amount of sleepless nights I had because of cocaine... I am talking about the Ruby Gem obviously ;)
@mastohost Did it cause any non-delivered posts or just delays?
@ondra just delays. In fact the federation would stop working and all posts would be queued. In theory no post should be missing but it only affected a couple of instances, that after restart were back to normal and just needed to wait for the queue to clear.
Patch is installed. It all looks good from my end but if you have any issues please let me know.
Thanks 🐘
