Mongrel users - Aug 2007 - Semi-OT: any tips on how to track down memory leaks?

hello list!

i seem to have a serious memory leak in my rails app that i run with a
bunch of mongrels on windows (as services).

i tried the MemoryProfiler i found at
http://scottstuff.net/blog/articles/2006/08/17/memory-leak-profiling-with-rails
but honestly i have no idea on how to read those string dumps. i tried
diffing them but nothing there made any sense to me.

any tips or hints would be greatly appreciated!

best regards
Ralf
