Hello All,
Long story short, we're in the process of load testing an application
built against Wicket 1.3 snapshot. Unfortunately we've seen some
server issues with sessions/page maps in the file store during
testing, and I was wondering how I'd go about programatically changing
the default page map size in DiskPageStore just to see if changing
this value affects what we're seeing.
FWIW, right now it looks like we're having issues under load with
Wicket creating too many open file handles on a fairly default install
of RHEL 5 which results in exceptions like this:
java.lang.RuntimeException: java.io.FileNotFoundException:
