Shortly after upgrading to Mbin 1.7.1-rc1, php ran out of workers. I dramatically increased the limit. It isn’t clear to me why that happened and if it’s related to the upgrade or just coincidental. My intuition is that it’s related, but I have no evidence.
Commenting here due to the timing of the issue: looks like no new posts have come in from federated instances for about 3 hours?
Thanks for reporting that - I am working to fix it - not sure what is going on yet
