Buffer leaks while running controller from OpenFlowPlugin distribution

Bug Verified Done Maros Marsalek Debolina Bandyopadhyay Thu, 15 May 2014 07:25:14 +0000 Tue, 25 Jul 2023 08:23:45 +0000 Thu, 26 Jun 2014 11:06:44 +0000 netconf Fri, 27 Jun 2014 00:00:00 +0000 0 5 <p>Hello,</p> <p>I have seen the error log over the past week. However, the issue disappeared after rebuilding the openflowjava and openflowplugin repositories (and running the openflowplugin distribution).</p> <p>Please try updating code and rebuilding the mentioned repositories. Report if the issue persists (the '-Dio.netty.leakDetectionLevel=advanced' log would help).</p> <p>Regards<br/> Michal Polkorab</p> <p>As the issue appeared again I tried to debug it.</p> <p>It looks like there is some buffer.release() missing in the netconf pipeline.
