Actual Behaviour

Getting the OutOfMemoryError in event loop thread as below, while creating allocating the memory to byte buffer array.

Error Logs :

Out total allocated heap size is 2GB and other config are as below :

If i look at the heap dump it tells that only 1.3GB has been consumed and our total allocated heap size is 2GB, then how come it could throw the OOM error as still 0.7GB is left.
