Our application uses XML document objects to store in-memory data cache. This has been working with no issues in JRun 3.1 for the past two years. But, eversince we deployed the application in WebSphere-5.0 (later in 5.1), the XML document tree looses the elements in a random order. For example, the XML tree loaded with 6000 elements at the application startup ends up only with < 100 elements when the application load is at its peak. This results data lose in the application cache. Strangely though, not always the same set of elements are disappearing. We suspect the JVM picks up the XML elements selectively for garbage collection(may be weak-reference). Did anyone had this issue? Any thoughts.    More>>
