Hi all,
We're running into a problem that we've seen happen many times though
unfortunately we can't consistently reproduce it. We're using Wicket
1.3.1 with automatic multi-window support enabled and the default
SecondLevelCacheSessionStore.
During normal use of our site, no Pages reference other Pages and the
session size changes as it should. However, occasionally when we open
pages in a new tab (often when multiple pages are opened in a new tab in
rapid succession), we get the following situation:
1 tab
pagemap-null size = x
2 tabs
pagemap-null size = 2x
pagemap-0 size = x
3 tabs
pagemap-null size = 4x
pagemap-0 size = 2x
pagemap-1 size = x
4 tabs
pagemap-null size = 8x
pagemap-0 size = 4x
pagemap-1 size = 2x
pagemap-2 size = x
The only explanation that I could come up with for this explosion is
that somehow, behind the scenes, a Page is holding onto a reference to
another Page in this situation. Because 8x is beyond our max pagemap
size, it means that there can only be 1-2 Pages in it taking up this space.
Has anyone come across a problem like this? Any thoughts on what this
could be?
Thanks,
Meetesh
