Memory profiling and Threads [message #138107]

I have a simple standalone app that spawns off a couple of threads.

When I profile it with any thing but the memory analysis tool, I get
meaningful data and expected behavior.

With the Memory Analysis tool, shortly after starting the first thread,
eclipse locks up consuming a fairly consistent 50% of the cpu.

Any ideas or suggestions?

Can you briefly describe the nature of the work the application threads
are doing? Do they allocate a large number of objects?

Also,
- Have you tried defining profiling filters to minimize the amount of
data collected?
Have you tried running the profiler in "standalone" mode from the
command prompt (see the online help for details)?

Thanks,
Asaf
