#3743
Столкнулись с проблемой повышенного потребления памяти процессами blockstore-vhost-server из-за VmPTE. Это происходит из-за маппинга памяти гостя в наш процесс. При этом чем больше дисков у ВМки и чем она жирнее, тем хуже проблема.
В качестве припарки я добавляю в конфиг параметр, который позводит включить сброс маппингов каждые N байт пропущенных через диск.
