Subject Re: My task managers are not starting

Strange. I decreased the max value (TM_MAX_OFFHEAP_SIZE) even it says the
slave will not use all space and it worked.

        # Long.MAX_VALUE in TB: This is an upper bound, much less direct
memory will be used
        # TM_MAX_OFFHEAP_SIZE="8388607T"
