Any status on this? Should this be an openflow plugin bug or belongs somewhere else (controller or yangtools)?

Comment by Flavio Fernandes [ 27/Aug/14 ]

Abhijit,

AFAIK, this issue is still there. Using today's (below) master:

https://gist.github.com/anonymous/530ad4bc7810407d6ea4#file-gistify838767-txt-L1316

$ cat version.properties
org.opendaylight.controller.version = 0.1
org.opendaylight.controller.build.scm.version = 597deaeac655af6bff79cb892165a1d5a32ea826
org.opendaylight.controller.build.user = jenkins-controller

Offending code is statistics manager, since it is only writer of that tree,
write conflict could be also caused by inventory manager, since they share subtree (e.g. inventory manager deleted node from operational, statistics manager was trying to write node).

Comment by Abhijit Kumbhare [ 27/Aug/14 ]

Added Anil on the cc.

Comment by Martin Bobak [ 02/Sep/14 ]

This bug is dependent on statistic manager's shift to new md-sal api and performance improvement. Need to revisit this issue when CONTROLLER-661 is solved and statistics manager is shifted to new md-sal api.

Comment by Martin Bobak [ 01/Oct/14 ]

This issue can't be reproduced.
