Comment 9 for bug 1401879

Unfortunately at this point there is no strict evidence that this bug has been caused by the fix for https://bugs.launchpad.net/mos/+bug/1381338

Database deadlocks are quite common issues with neutron DB access which don't have simple solution.

The issue observed here has not visible user experience impact, however apparently it lead to inability of agents to update their status on neutron server, which then may lead to various failures.

The fix proposed for this bug is more a safety measure against possible negative side effect of the fix for https://bugs.launchpad.net/mos/+bug/1381338
