Mid-Tier hangs. Restarting the Apache Tomcat service clears the problem. The service doesn't crash so our service monitor doesn't detect it as a failure. The client sees a the error information listed below. Anybody else seeing this problem? We're using the servlet and IIS.

Are you using the Tomcat web component as well as the servlet, as opposed to using the servlet with IIS which requires the JK connector. Using the connector negates any improvements over IIS/SE, so we are testing both IIS/SE and the Tomcat 5.5 standalone configurations, as recommended by the October 2006 benchmark comparison of the ServletExec and Tomcat engines. Tomcat 5.5.17 has been fairly stable during our testing (one JVM-induced crash on x64 server) since I set the memory pools to 512 MB and 1536 MB in the Java properties. The prefetch process gives you a good stress test - ours runs 35 minutes (ITSM 7 minus Asset) and keeps the AR server at 30% CPU utilization the whole time. The mid-tier server using Tomcat has very little CPU usage during this time, but the one using IIS/SE has a steady 10 to 25% CPU usage.

Other than some instability of the Mid-tier, which is apparently caused by the Apache Tomcat component, we're seeing no problems. We upgraded from 5.1. We have 20+ applications in production, all home-grown.

If so, how is your experience so far? Is it stable once you have it up and running? We are thinking about upgrading ARS, Midtier and Service desk. We also have some homemade applications that need to work on the new platform. Our ARS is currently on version 4 and the Helpdesk is on 6.3 (yes, it's old, but also exceptionally stable).
