When running my simple pipeline from time to time I'm getting below exception:
Caused by: java.io.IOException: Insufficient number of network buffers: required 1, but only 0 available. The total number of network buffers is currently set to 2048. You can increase this number by setting the configuration key 'taskmanager.network.numberOfBuffers'. at org.apache.flink.runtime.io.network.buffer.NetworkBufferPool.createBufferPool(NetworkBufferPool.java:196) at org.apache.flink.runtime.io.network.NetworkEnvironment.registerTask(NetworkEnvironment.java:298) at org.apache.flink.runtime.taskmanager.Task.run(Task.java:469) at java.lang.Thread.run(Thread.java:745) I'm using trunk of Beam with FlinkRunner. I guess it's well known Flink problem? Idea how to prevent it? Pawel
