Hi Norbert,

you may want to put one of your app names {seaside. magritte. magma} and one of the class names into google search. The search result connects you immediately to the collective knowledge of the Squeak community, example:

- http://www.google.com/search?q=weakarray+seaside

Besides of that, you can look for class references and find the guilty who send #new or #new: to one of the classes.

Hi Norbert,

the tool is Smalltalk, just inspect

(((Smalltalk allClasses collect: [:each | each name -> each instanceCount
])
reject: [:each | each value = 0])
asSortedCollection: [:a :b | b value < a value]) asArray

This gives # of objects per class, in a nice GUI :-)

Thanks, this is quite good. I have now a statistic like:

246565 WeakArray
241929 WeakKeyAssociation
179848 ByteString
171165 Array
159003 Association
130254 WeakValueAssociation

What is the best way to determine where this instances are
referenced. Do I have to use PointerFinder or Smalltalk
browseAllObjectReferencesTo: or is there better way?

thanks for your help, this goes also to Ramon and David.
You are very helpful, guys.

Norbert
