Problem summary
**************************************************************** * USERS AFFECTED: Users filtering searches by 'Person' in * * Process Inspector. * **************************************************************** * PROBLEM DESCRIPTION: A StackOverflowException may occur * * when filtering by 'Person'. * **************************************************************** * RECOMMENDATION: * **************************************************************** When executing filtered searches in Process Inspector under the Process Admin console by 'Person', a user may encounter a StackOverflowException during runtime. The issue may be seen when a large number of participant groups(PG) are created for a process application. The error may be more apparent if there are a large number of snapshots created as each snapshot will contain a copy of the PGs. A similar error can be seen in the logs: com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0014E: service() ?? ??{?? RestAPIServlet ????????: javax.servlet.ServletException: java.lang.StackOverflowError at org.apache.wink.server.internal.RequestProcessor.handleRequest(R equestPr ocessor.java:195) at org.apache.wink.server.internal.servlet.RestServlet.service(Rest Servlet. java:124) at javax.servlet.http.HttpServlet.service(HttpServlet.java:668) A temporary workaround for this situation would be to archive and delete old snapshots that are of no use. This would eliviate unneccessary looping through the old snapshots.
Problem conclusion
Code changes have been made to resolve the StackOverflowException and properly return the correct results. An interim fix is available on v8.0.1.1. The fix will be integrated into the next fix pack.
