 Description   

As indicated in MD-SAL meeting, I'm opening a bug to track this issue

https://meetings.opendaylight.org/opendaylight-meeting/2014/md_sal_interest_call/opendaylight-meeting-md_sal_interest_call.2014-08-05-16.12.html

It is hard to do development with this bug, because this error log is very chatty.

Comment by Tony Tkacik [ 06/Aug/14 ]

This logs are introduced by incorrect writes, probably offending code is stats manager

Comment by Martin Bobak [ 08/Aug/14 ]

Statistics manager is being shifted to new MD-SAL API. Waiting with further investigation of this issue for API shift to be done.

Comment by Martin Bobak [ 18/Aug/14 ]

Shifting TopologyManager and InventoryManager to new MD-SAL API, along with hot fix in https://git.opendaylight.org/gerrit/#/c/9982/ are solving this issue.
