Problem with jmap -dump

843798Feb 21 2007 — edited Nov 13 2007

Hello,

we try to fix a performance bug in our webapp. There for we use the Java 6 Monitoring capabilities. On the test-mashine the dumping is fine. On the live server, the created dumps are not readable by YourKit Profiler.

Here's the output

[weblog@www weblog]$ /usr/java/latest/bin/jmap -J-Xmx512m -dump:format=b,file=/release/hdump.hprof -F 23901
Attaching to process ID 23901, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 1.6.0-b105
Dumping heap to /release/hdump.hprof ...
Unknown oop at 0xb01928c0
Oop's klass is null
Heap dump file created

Any ideas how to solve this problem? thanks
