Hi,

Something in VPP (most likely my UPF/GTP plugin) is causing an abnormal
high virtual memory consumption. `show memory` without and with
memory-trace enable can not explain it.

With some 10k sessions I see as much as 1TB virtual memory usage, but only
about 200MB or so residential memory. `show memory` also only reports about
200MB.

My best guess is that something requests virtual memory pages from the OS
and does not return them.
Any hint on how to track this down? What in VPP could request that much
virtual memory without actually using it?

Many thanks
Andreas
