That's pretty much what I did as well. Most of the objects were
strings, bytes, dictionary buckets - stuff that's used just about
everywhere. Trying to get a meaningful set of !gcroot samples from
amongst 125 000 dictionaries manually is a bit difficult :|.
My hope is that somewhere in that list there is an object that leaks 1
instance per request, so that I can match it up with the number of
requests, and work from it to figure out what's going on.
