Hi Ufuk,
so the memory available per node is 48294 megabytes per node, but I reserve
28 by flink conf file.
taskmanager.heap.mb = 28672
taskmanager.memory.fraction = 0.7
taskmanager.network.numberOfBuffers = 32768
taskmanager.network.bufferSizeInBytes = 16384
Anyway Follows what I found in log files.
*Follows the taskmanager log (task manager that seems failed)*
