The HPROF binary format limits records to 4GB so the heap dump record in version "JAVA PROFILE 1.0.1" cannot accomodate very large heaps. The jmap utility should be updated to support "JAVA PROFILE 1.0.2" which allows for large heaps to be split into a sequence of dump records. For compatibility it would be best if jmap continued to generate a 1.0.1 format for smaller heaps (<2GB for example).
