Description Jesse Glick 2009-03-05 21:37:01 UTC

I am trying to load a 529Mb heap dump in the IDE. My IDE uses default max heap for my 3.2Gb RAM, i.e. 512Mb. The
progress bar has been showing "Loading Heap Dump..." for several minutes now, with heavy disk activity. There is no
indication of what percentage of the heap dump has been loaded. If it is simply too big to handle and I need to stop
loading it, it seems that I would need to restart the IDE, since there is no cancel button either.

BTW its activity:

Finally done! My IDE's heap usage is not up by much, which is good.
