Comment 5 for bug 1794991

Hey Swaminathan, thanks for answering !

We have 8 instances on this network spread like this:
  - 1 on compute002
  - 1 on compute003
  - 3 on compute005
  - 3 on compute007

The only RPC timeout we got are these one (they are not related to any port of our network/instances with issue):
