Restarted the tomcat services. deleted the temporary internet files from the web browser. We have ARSystem v.7.1, ITSM 7.1 no patches. Recently upgraded to Mid-Tier 7.1 patch 7. Tomcat 5.5.25 Tomcat does not crash at all. But, somehow when we are trying to access the in-house built application through mid-tier I'm getting this HTTP 500 status message as shown in the previous posting.
