Subject sporadic occurance of an EmptyStackException ...
Date Wed, 19 Feb 2003 09:57:37 GMT
Hy,
Sometimes i get following exception, when i call my cocoon-app.
When i recall the very same URL in general everything is OK. In
rare cases the problem vanishes after two retries, but sporadically
returns.

Did anyone encounter similar problems and possibly has an idea,
what i might do wrong ?

im using: cocoon-2.0.4
           tomcat-4.1.18
           os=solaris-2.8

           cocoon runs as the default application in tomcat
