Hi,
*) If the percent to reduce storage is set to 10%, it fails to
remove any when the number of items are below 10. The number of items
to be
removed needs rounding upwards. Why not remove a fixed number of items
instead of a percentage? (My idea and now I think it was wrong!!)

Hi Gerhard,
I've tested your latest Store Janitor improvements (using Optimizit and
your debug messages) and although its a very great improvement, I've
found some other problems :-(
As my Optimizit trial was running out I decided to do some urgent work
on the Checker and now have a solution

People,
What's your opinion on adding size() method to the Store interface?
Currently method of getting store size by enumerating through all store
items employed in MRUMemoryStore does not fill me with optimism...

Hi Team,
I hope I fixed the problem now!
I changed the StoreJanitorImpl, I try to explain in
prosa:
Cocoon reaches 1 million request per second and
memory is getting dangerously low. Time for the
StoreJanitor to kick in and do something. First
he forces the GC. Damn, memory is still low,

Hi Folks,
Its great to see such enthusiasm - thanks for listening. Just got a
coupe of comments and a simple idea that might help towards the solution
- if you scroll down.

Hi Gerhard,
I'm posting this separately under the same heading because it's probably
less relevant.
While analysing the store-janitor code I found some strange things in
the way Store-janitorImpl.freeMemory() increments the store index.
I assume that each successive call to freeMemory() is in

Slowly but constant this Store issues are a PITA for me :-/. I don't know

Hi Gerhard and Team,
I'm posting in this group now I think I found a design problem with
store-janitor.
I think store-janitor works fine when it can free sufficient memory by
calling the finalize and garbage collection. But if it needs to free the
store it locks up!
The reason it appears to
