Hi! I have a problem with one my web project. Sometimes in peak hours my application hangs, not writing log files and seems do nothing. In first time I suggested what VM is dead / halted for some reason, but it still works in that cases but do nothing ( and no logs! ). I used debug tool ( GitHub - utkarshkukreti/ex_top: ExTop is an interactive monitor for the Erlang VM written in Elixir. ) to connect to my erlang node in this moment and see this ( screenshot ).
You see, there are multiple :io.execute_request/2 calls what are not executed , just accumulate incoming messages to queue ( and do nothing! )
Any suggestions what it is and how to fix it?
