I believe that my configuration is already wrong but I would like to confirm with the community to understand the matter better. I have 4 middle managers (r3.2xlarge) running with a total of 28 slots. I’m using 17 slots. However, some of the tasks failed with this error.
OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00007fd5140bf000, 506040320, 0) failed; error=‘Cannot allocate memory’ (errno=12)
