This is caused by infinite loop of flushing and closing AbstractOutboundQueueManager in ofjava - sometimes (on disconnect) there can be still some unflushed segments but thery are not able to be flushed if channel is not writable anymore. In local testing we got stuck with cpu on 97%</p> <p>Operating System: All<br/> Platform: All</p> OPNFLWJAVA-79

Infinite reschedule of flush

Is this a BLOCKER such that we cannot release Boron without it? Is there a workaround such that we can write a release note and fix in future Boron SR1?<br/> Testing: Could you also elaborate on the testing of this patch? How extensively has this patch been tested? Is it covered by any unit tests or system tests? <br/> Impact: Does this fix impact any dependent projects?</p> <p>Severity<br/> This bug is quite serious thing since we stays with cpu usage nearly 100% almost everytime after openflowplugin cbench performance test is finished. This could be a security vulnerability as mentioned here: <br/> <a href="https://bugs.opendaylight.org/show_bug.cgi?id=6176#c6" class="external-link" target="_blank" rel="nofollow noopener">https://bugs.opendaylight.org/show_bug.cgi?id=6176#c6</a><br/> The issue was found during analysis of <a href="https://jira.opendaylight.org/browse/OPNFLWPLUG-727" title="cbench throughput test does not work in Boron" class="issue-link" data-issue-key="OPNFLWPLUG-727"><del>OPNFLWPLUG-727</del></a> which is already blocker and should help to resolve it. We don't see there a possibility of workaround.</p> <p>Testing<br/> There aren't any unit tests for modified part of ofjava. Actual internal integration tests passed successfully. We also successfully reproduce csit job locally <a href="https://jenkins.opendaylight.org/releng/job/openflowplugin-csit-1node-cbench-performance-only-boron" class="external-link" target="_blank" rel="nofollow noopener">https://jenkins.opendaylight.org/releng/job/openflowplugin-csit-1node-cbench-performance-only-boron</a>. There aren't CSIT jobs for openflowjava because it should be covered by openflowplugin CSIT tests.</p> <p>Impact<br/> The fix impacts openflowplugin project, positively, we belive.</p> <p>merged in boron</p> <p>This is fixed now according to:</p> <p><a href="https://jenkins.opendaylight.org/releng/job/openflowplugin-csit-1node-cbench-performance-only-boron/" class="external-link" target="_blank" rel="nofollow noopener">https://jenkins.opendaylight.org/releng/job/openflowplugin-csit-1node-cbench-performance-only-boron/</a></p> <p>BR/Luis</p> <p>Thank you Luis for tracking.
