I posted this the other day, I think I have some more information. Is there a way to change the session secondlevel cache store and possibly the default disk store such that there aren't collissions between file writes/reads. I think in a high volume environment (lots of hits), I am getting this pageexpiredexception because wicket is trying to access to the diskpage store data the same time. E.g. Are multiple writes/reads allowed against the diskpagestore/DiskPageStoreIndex?
- ------------- I get two pageexpiredexception errors and I can't recreate the problem. With an error like this, what would cause this type of page expired exception error? Do you think that the page actually expired? Or is there something wrong with writing or reading from the page map file on disk.
