It seems that it occurred due to accessing same ArrayList&lt;FlowEntryInstall&gt; object at same time. (I attached stack trace.)</p> <p>And I saw ForwardingRulesManager.java, but it seems that a execlusive controll for common resources(nodeDB, groupDB and so on) is not implemented in ForwardingRulesManager.updateNodeFlowsDB() and other methods of ForwardingRulesManager. There may be same probelms in other methods of ForwardingRulesManager.java.</p> <p>please let me know, if you have any questions.</p> <p>Operating System: All<br/> Platform: All</p> CONTROLLER-34

ForwardingRulesManager.updateNodeFlowsDB() is not thread-safety.
