@grumbulon if the pools are too small then your instance will run out of oban runners and start failing to serve things like notifications or threads depending on which are all used-up. I was able to see things start to choke and die when I lowered them too much. I lowered them all by like 50% and then I lowered some of them more until things started eating shit and raised them back up until it kind of stopped. Eventually I gave up and threw more cpu at the problem and raised them all again until blink stopped complaining
