It happened after redundant ring testing, when all nodes rejoined and normal traffic was restored (both rings functional).

Having cpgbench traffic might help reproducing the issue, for me it was like 2/10.

Jaroslav,

Is this a redundant ring only bug?  (Does this happen on single ring setups in your lab environment?)

Thanks
