I’ve got a 2-container install on a DO 8GB droplet that is behaving very strangely.
There is a postmaster (EDIT: now there are two of them) processing eating 100% CPU.
Sidekiq is running, but the Dashboard complains that it’s not checking for updates.
There are some logs like
PG::ConnectionBad (FATAL: remaining connection slots are reserved for non-replication superuser connections ) /var/www/discourse/vendor/bundle/ruby/2.4.0/gems/pg-0.21.0/lib/pg.rb:56:in `initialize'
Job exception: FATAL: remaining connection slots are reserved for non-replication superuser connections
The data container has:
db_shared_buffers: "2GB" db_work_mem: "40MB"
There are 4 unicorn workers in the web container (same as # processors).
