Hi All I investigated some more and checked the line mentioned in the NPE stacktrace:
It seems to be caused by call to the object returned by IPSecurityManager.Factory.getInstance(), which means that the getInstance method returns a null reference. Can anyone think of situations where this could happen? cheers Claudio -----Ursprüngliche Nachricht----- Von: [email protected] [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 22.

However after a couple of hours, sometimes days, the author instances stopp working. Tomcat displays the following error message instead of the magnolia login: HTTP Status 500 java.lang.NullPointerException info.magnolia.cms.security.URISecurityFilter.isAllowed(URISecurityFilter.java:70) info.magnolia.cms.security.BaseSecurityFilter.doFilter(BaseSecurityFilter.java:59) info.magnolia.cms.filters.AbstractMgnlFilter.doFilter(AbstractMgnlFilter.java:70) info.magnolia.cms.filters.MgnlFilterChain.doFilter(MgnlFilterChain.java:71) info.magnolia.cms.security.LogoutFilter.doFilter(LogoutFilter.java:81) info.magnolia.cms.filters.OncePerRequestAbstractMgnlFilter.doFilter(OncePerRequestAbstractMgnlFilter.java:62) info.magnolia.cms.filters.MgnlFilterChain.doFilter(MgnlFilterChain.java:71) info.magnolia.cms.security.auth.login.LoginFilter.doFilter(LoginFilter.java:76) info.magnolia.cms.filters.AbstractMgnlFilter.doFilter(AbstractMgnlFilter.java:70) info.magnolia.cms.filters.MgnlFilterChain.doFilter(MgnlFilterChain.java:71) info.magnolia.cms.filters.ContentTypeFilter.doFilter(ContentTypeFilter.java:73) info.magnolia.cms.filters.AbstractMgnlFilter.doFilter(AbstractMgnlFilter.java:70) info.magnolia.cms.filters.MgnlFilterChain.doFilter(MgnlFilterChain.java:71) info.magnolia.cms.filters.ContextFilter.doFilter(ContextFilter.java:72) info.magnolia.cms.filters.AbstractMgnlFilter.doFilter(AbstractMgnlFilter.java:70) info.magnolia.cms.filters.MgnlFilterChain.doFilter(MgnlFilterChain.java:71) info.magnolia.cms.filters.CompositeFilter.doFilter(CompositeFilter.java:64) info.magnolia.cms.filters.AbstractMgnlFilter.doFilter(AbstractMgnlFilter.java:70) info.magnolia.cms.filters.MgnlMainFilter.doFilter(MgnlMainFilter.java:98) info.magnolia.cms.filters.MgnlMainFilter.doFilter(MgnlMainFilter.java:195) I get these quite regularly, and sometimes have to restart like 5 times until it doesn't happen again. This makes installing updates on the server that involve restarts quite painful. Did anyone experience the same or has an idea how to fix this?
