Help troubleshooting DBConnection client exit errors

Questions & Help Questions

We use postgrex directly, and have started to occasionally see the following error:

[error] Postgrex.Protocol (#PID<0.1855.0>) disconnected: ** (DBConnection.ConnectionError) client #PID<0.62.69> exited

I could be wrong, but I think the error originates from db_connection/lib/db_connection/connection_pool.ex at master · elixir-ecto/db_connection · GitHub

But I have no clue what the actual cause is.

Is there no other mention of the pid (here 0.62.69) in your logs?
