Hi!
If my supposition was right, memory usage should be constant. So,
I assume it has enough space. Also, I see a clear degradation in the
performance during the cycle, so I suppose something is really going
wrong.

Hi!
I'm having an Out of memory exception (and consequently
application death) that I can't figure out why it happens. I
suspect it's because I'm assuming something about the WO behaviour
that is not correct (as usual).
The problem is this: I have an action that creates some test
data. Depending on the parameters I feed on the page, it may
create many many objects (50k, or more). Of course, this takes
time, and the request will at some point hang (ie, the browser
gets an error from the adaptor) but I don't care, as this is used
only during testing.
I suppose you gave enough heap space to the java VM (max 2GB). Per
default, the heap size grows exponentially. To make the VM less
greedy, I start my apps with
-Xms256m -Xmx2048m -XX:NewSize=128m -XX:MaxNewSize=128m
Mit freundlichem Gruß,
