There is a constructor parameter in DiskPageStore constructor (the last int parameter) that says how many handles DiskPageStore will keep opened.
But the default number of file handles is 50. If this is causing your server file handle problems than you should consider changing the configuration. Are you sure there are no other file handles leaking? What are the files opened? -Matej On 11/8/07, Brandon Harper <[EMAIL PROTECTED]> wrote: > Hello All, > > Long story short, we're in the process of load testing an application > built against Wicket 1.3 snapshot.
