Is there a way to dump the objects in memory from a running ruby process?

Question

Killing the processs while obtaining this information would be fine.

Answer 1

A quick-and-dirty way would be ObjectSpace.each_object{|e| p e}. You could do some tests to determine what you wanted to keep, or Marshal the objects.

Answer 2

For the more hardcore there is also BleakHouse which gives you a special custom-compiled copy of ruby with better memory leak tracking powarz
