This could lead to agents flapping and various issues such as sporadic reschedluing, port binding failures, etc. Change-Id: Ief392f9a09d86c185dc086055d2cbc1891ff1d7f Closes-Bug: #1560724 ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo!

The reason for this error is mysql backend configured as multi-master cluster. Usual solution is to apply retries here, which was not done for this particular case. As a result of this deadlock various side effects could arise such as agents become dead, port binding failures or resource rescheduling.
