I am seeing constantly and slowly growing memory usage on my production app that is deployed to fly.io.
In the vm when I run top I can see that the size of the beam.smp process uses this memory.
I checked in the phoenix dashboard and with :observer the memory use and in those I only see ~350mb.
(the images are not from the same time, but they match up)
Any idea how can I find what is using this memory?
