> -----------------------------------------------------------------------
>
> Key: FLINK-9636
> URL: https://issues.apache.org/jira/browse/FLINK-9636
> Project: Flink
> Issue Type: Bug
> Components: Network
> Affects Versions: 1.5.0, 1.6.0
> Reporter: zhijiang
> Assignee: Nico Kruber
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.5.1
>
>
> In {{NetworkBufferPool#requestMemorySegments}}, {{numTotalRequiredBuffers}} is increased by {{numRequiredBuffers}} first.
> If {{InterruptedException}} is thrown during polling segments from the available queue, the requested segments will be recycled back to {{NetworkBufferPool}}, {{numTotalRequiredBuffers}} is decreased by the number of polled segments which is now inconsistent with {{numRequiredBuffers}}. So {{numTotalRequiredBuffers}} in {{NetworkBufferPool}} leaks in this case, and we can also decrease {{numRequiredBuffers}} to fix this bug.
