Hi,

Whenever I try to read .hprof file with the command:

c:\> hat myheap.hprof

I get the following error. This is happening majorly with IBM JRE.

java.io.IOException: Thread 200001 not found for JNI local ref
at hat.parser.HprofReader.getThreadObjectFromSequence(Unknown Source)
at hat.parser.HprofReader.readHeapDump(Unknown Source)
at hat.parser.HprofReader.read(Unknown Source)
at hat.parser.Reader.readFile(Unknown Source)
at hat.Main.main(Unknown Source)


Is there any solution?

Thanks,
Guru

Have you tried with the Sun JVN/JRE, it might not like the Sun vs IBM cross pollution...

I have no problem with SUN JRE, only problem with IBM JRE.

Thanks,

I thought that might be the case. Honestly I don't know if there is a solution to using the IBM JRE, I doubt that they will play nicely together
