Hallo Georg,
Thank you for your answer.
I do know that page and have read it before, just reread it again.
What bothers me is:
If I have a snapshot, how long will it be around? It will have a weak
reference, when a new snapshot is created (5.2 and later). Does that
mean it will eventually be garbage collected even if the editingContext
it resides in is not garbage collected? Or does it need to be
decremented to 0 until it is released? How many snapshots of the same
table data does it need for one snapshot to be decremented to
0/released/ freed for garbage collection?
Perhaps I'm not seeing the trees in the wood, but I do have to get
memory usage down and this could be a possibility why emory usage is so
high in the first place, perhaps.
Regards,
Ute

Hi Ute,
have a look at

Caching_and_Freshness
(Yes, I just posted it before Mike Schrag could do so :-)
This will give you some insights how to treat this very common kind of
problem.

Hallo,
Does anyone know whether WebObjects will keep old snapshots in his
memeory, i.e. I have a very log timestampLag. So WebObjects has some
data fetched, then the data is needed again and fetcht again... will
it keep the first fetch/snapshot or will it get rid of that or
repopulate it?
Thanks for some clarification,
Regards,
Ute
