Hi, there.
- I'm running:
Weblogic 9.2 MP4
Sun JDK 1.5.0_22 (32bits)
Solaris/Spark
- JConsole reports Heap Memory Usage ranging between 200MB and 450MB.
- I generated a 237MB dump through the following command:
jmap -heap:format=b <pid>
- During dump generation jmap reported several of these:
Unknown oop at 0xeb5d12a0
Oop's klass is null
Finding object size using Printezis bits and skipping over...
- When I open the dump with MAT, it reports:
Size: 63,2 MB Classes: 14,4k Objects: 1,1m Class Loader: 647
- If I open the Unreachable Objects Histogram I can see the sum of the 15 bigger shallow heap sizes reach about 125MB.
Do you think this dump file was correctly generated?
Is it consistent with what JConsole reports?
Kind regards
