Are any of your applications using Xalan/Xerces?  We have seen this in
the past, particularly if you use the XPath or CachedXPath capabilities
of Xalan or when doing XSL transformations.

Subject: [ServletExec] JNI int[] references not being cleaned up by GC





   Hello.  We have been profiling memory usage and have been noticing
that JNI references are not being cleaned up in ServletExec even after
45 min.  We are seeing a large growth 2-3MB of int[] arrays with each
request that goes through ServletExec.  (We are using IIS 5.1 and
ServletExec ISAPI 5.0.)  Has anyone else seen this issue?



   - Catherine
