Thanks, I’m not exactly familiar with how all max thread limits affect each other. So I reverted all environment settings back to default, increased the postgresql limit, and the issue still shows. What could be the next debugging step, or what should I try now? PS. From what I’ve read (link below), this issue has likely not to do with postgresql but with rails configuration. That’s why I tried upping/changing the rails thread limit environment variables. https :// judoscale .com/blog/active…
