nit: "This is not recorded in case of account status check failure."

do you plan to investigate why this happens?

I don't expect this happens in real time (probably timeout in case of CPU
overloaded). If I see noticeable number of such errors I will take a look. At
this stage it is important for me % of normal flow.
