Description Sai Sindhur Malleni 2017-09-01 22:59:44 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 the following in neutron server logs:

Comment 1 Mike Kolesnik 2017-10-18 08:52:56 UTC

Unfortunately it's hard to understand the cause for this from the short log snippet, without having full logs.

I suggest we close this bug for now and reopen when we have enough data to reproduce it, unless you miraculously have the logs for this somewhere and can provide them.

Comment 2 Mike Kolesnik 2017-10-29 07:52:25 UTC

Closing for now since we don't have the details, let's re-open if we have logs or something more concrete..
