On our customer site though we found a different error in the
website-jvm-stderr.log. There it says "Class not found" and then returns 404 for
all the requests
2006-02-22 09:34:16 - Ctx(/website) : Class not found: cirs
2006-02-22 09:34:16 - Ctx(/website) : Status code:404 request:R( /website +
/servlet/cirs + null) msg:null
This happens failry regularly for all the servlets we have and there is no fixed
pattern for it.
2006-02-24 07:31:48 - Ctx(/website) : Class not found: cirs
2006-02-24 07:31:48 - Ctx(/website) : Status code:404 request:R( /website +
/servlet/cirs + null) msg:null
2006-02-24 07:31:48 - Ctx(/website) : Class not found: wt
2006-02-24 07:31:48 - Ctx(/website) : Status code:404 request:R( /website +
/servlet/wt + /callersu) msg:null
We are frustrated with these repeated failures.
Thanks,
-Prashant.

This looks like one of the many reloading fixes since 3.3.1, and since I can't
reproduce this.....
If you can't upgrade to 3.3.2, then I would suggest that you configure your
context as non-reloadable (which is the preferred configuration for a
production environment anyway :).
In conf/apps-website.xml you do:
<webapps>
<Context path="/website" docBase="webapps/website" reloadable="false" />
</webapps>
Alternatively, simply comment out the ReloadInterceptor in server.xml
