Yes, this is normal. > 2) What Tomcat activity is consuming the heap? Depends on what connectors you have configured, your watched resources, autoDeploy settings, etc. All of these are creating objects as they run, even if they find nothing to actually work on. You can enable a heap profiler to see the exact objects and who's creating them. > 3) Presumably this means that in planning for a memory restricted > Tomcat + apps, one needs to apportion about 22MB to the Tomcat heap, > apart from heap allocated to applications. Sounds reasonable, although the base value will vary somewhat depending on config settings, Tomcat version, JRE version, OS, and platform. When sizing, don't forget about PermGen usage, which is not part of the heap and is largely dependent on the number of classes in your webapps. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
