> OutOfMemory error (Direct buffer memory)
> ----------------------------------------
>
> Key: FLINK-2865
> URL: https://issues.apache.org/jira/browse/FLINK-2865
> Project: Flink
> Issue Type: Bug
> Components: Distributed Runtime
> Affects Versions: 0.10.0
> Reporter: Greg Hogan
> Assignee: Maximilian Michels
> Fix For: 0.10.0

> I see the following TaskManager error when using off-heap memory and a relatively high number of network buffers. Setting {{taskmanager.memory.off-heap: false}} or halving the number of network buffers (6 GB instead of 12 GB) results in a successful start.
