Description

This happened after updating to 18.* branch. At this moment I have 18.03.0-ce-rc4-win57 (16511) build and my vpnkit.exe steals gigabytes of RAM in 2-3 hours with 2 containers running.

Like this:

2018-03-25 18-00-20

Or even like this:

2018-03-24 16-10-41

I think it should never consume about 8 GBs of my RAM.

Research direction

Start with the vpnkit.exe memory-growth report for build 18.03.0-ce-rc4-win57, reproducing it with two containers over 2–3 hours. Trace the component responsible for the increasing memory use and verify that the process no longer grows to gigabytes under the reported workload.
