The issue was caused by problematic changes to AdGuard DNS software configuration. We increased GOGC variable which basically means that we exchanged RAM for CPU usage. The problem is that the configured value lead to huge RAM usage spikes and the OOM killer aborting the AdGuard DNS process in result.
