Hello all

I'm trying to open several hprof heap dump files generated using " jmap -dump " on jdk 1.6.0.11.
The heap dumps are rather large.. 3gb..
I'm using MAT Version 0.8

I'm running this on a Linux box (which is 32bit)

I keep getting this message while mat is parsing the hprof file (at around 10/11 %) :

Parser found 0 HPROF dumps in file 4784.hprof. No heap dump index 0 found. See FAQ.

I can't get much information about this error and the eclipse wiki page just says to set a variable called MAT_HPROF_DUMP_NR=<index#> .


The entire log is shown below:

!ENTRY org.eclipse.mat.ui 2 0 2010-03-09 17:04:00.320
!MESSAGE (Possibly) Invalid HPROF file: Expected to read another 3,045,990,844 bytes, but only 853,675,592 bytes are available.

Any ideas why this is happening?

Thanks
Liza
