Observed, that metrics stop accumulating, resulting in zero values and in Prometheus

No specific pattern observed

Additional Information

Probably, we should update the version of the app, now we use 0.9.0 (from mid-2019) while the latest version is 1.4.2.

Flong with the issue, we see non-informative logs about connection resets. This was also fixed in mid-2020
