Greg Hogan created FLINK-2865:
---------------------------------
Summary: 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
Reporter: Greg Hogan
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.
