Description Sai Sindhur Malleni 2017-09-01 22:41:01 UTC
Description of problem:

When running a Browbeat+Rally use case which does:
Create a network
Create a sbunet
Create a router
Attach router to subnet and oublic network
Boot VM with floating IP
Ping VM

with concurrency 8 and times set to 50 we see that some VMs remain unpingable even after 300 seconds and we see a lot of the following exceptions in karaf logs
