Getting "view could not be restored" error, has anyone seen this before?

[Chris Stewart]

I'm getting this error in my logs and cannot figure out why I'm seeing this. In my web.xml I have an element to specify no session timeout. I'll post that below as well.

ViewExpiredException

You have your session timeout set to 0 and I'd have to RTFM to verify that that means "don't expire".

I've never done an app with infinitely-long sessions, however. I figure if they go for more than a day or 2 between page clicks, %$^%@ 'em. Those sessions cost resources, and if they're not eventually freed up, the resulting leaks will blow out the server.

[Chris Stewart]

Oh wow, good point. I never even put it together but we have seen OutOfMemory exceptions every 7 days or so. I'll set the timeout to something and see if I can handle that exception gracefully. Any tips on that?
