yes, this is a generalized problem in Roller and I believe we already
have a Jira issue defined for this. I think the key is that we need to
do a better job of detecting these kinds of errors/situations and taking
the appropriate action. I think one way to help this is to continue to
trim down the RollerRequest class, which is kind of a black box where I
think some of these issues may be coming from.
also, AFAIK the blank page issue that happened in the past and somebody
mentioned having recently is basically the same situation. there is an
error being generated in one of the view servlets, but it is not being
properly caught and handled, so the caching filters to get notified.

Hello,
Everytime someone tries to hit a "dead" blog I get this massive
exception in my roller.log file.
[listing 1 below]
Don't I just need a note that there was a 404 on the non-existing blog
"name of blog".
Is there something I can change in my log4j properties to fix this up?
Or should I enter is a feature improvement.
Thanks for any suggestions.
