Comment 5 for bug 1510327

The above log will be useful if you can tell us which test failed (I can't from that log) and how the issue can reliably reproduced. It will be much easier if you just provided the stack trace in your setup.

Can we also do the following:
* When the infinite loop happens, immediately stop the neutron server,
and then restart it. This will stop overwhelming the log and the
neutron server process.
* Now check which subnet was leading to this error, and find what are
the associated GBP and Neutron resources with this subnet (L3P, L2P,
PTG, neutron network and neutron ports).

And as before, it will help to get the exact sequence of steps that is
leading to this (is the L3P, L2P being implicitly created, is this
happening after a provide/consume and if so is there a redirect to a
contract involved, etc.)
