Cisco CSR 1000v memory usage on ESXi

Hello all,

Recently we deployed some CSRs on ESXi 6.5 u2, they run fine.

I have noticed that vsphere is reporting that the VM's are triggering the "Virtual Machine memory usage" alert.

2 different CSRs on different hosts, dedicated to these routers.

4 vCPUs and 8GB of ram per CSR.

The hosts have nothing else on them and have 32GB RAM, so I'm lost as to why these VM's are reporting high memory usage.

Vsphere shows that they are using the full 8GB.

8192 MB, 8192 MB memory active

The kicker is that the actual routers are functioning just fine, I've had Cisco confirm what I see, the memory usage looks fine.

sh proc mem

Processor Pool Total: 2450272320 Used: 334367648 Free: 2115904672

lsmpi_io Pool Total: 3149400 Used: 3148568 Free: 832

Has anyone seen this before ?

Thanks peoples!
