Hi,

I tried with process=1 and it reached 1016 connections to rabbitmq.
lsof
https://paste.xinu.at/jGg/

i think it goes into error when it reaches 1024 file descriptors.

I'm out of ideas of how to resolve this. I only have 3 clusters available and it's kinda weird and It doesn't scale.

No issues here with 100s of clusters. Not sure what doesn't scale.

* Maybe your rabbit is flooded with notifications that are not consumed?

* You can use way more than 1024 file descriptors, maybe 2^10?

Sure looks like RabbitMQ. How many workers do have you configured?

Could you try to changing the uwsgi configuration to workers=1 (or processes=1) and then see if it goes beyond 30 connections to amqp.
