Peter,
I am running Weblogic as a server from within Eclipse so I will need to sendSignal tool you mention.

I am using Eclipse 3.3.2 and Weblogic 8.1 sp6 on my Windows box and am trying to do some profiling of our application to track down some memory leaks. I am using MAT and it relies on heap dumps for its profiling. I can have set up the vm args as follows:
-XX:+HeapDumpOnOutOfMemoryError -XX:+HeapDumpOnCtrlBreak

I get Heap dumps when I run out of memory but have not been able to figure out how to get the CTRLBREAK memory dumps.

How exactly do I execute a ctrl break???
