[jira] Created: (RVM-872) lusearch hangs with the production build

lusearch hangs with the production build
----------------------------------------

                 Key: RVM-872
                 URL: http://jira.codehaus.org/browse/RVM-872
             Project: RVM
          Issue Type: Bug
          Components: MMTk: GenCopy
    Affects Versions: 3.1.0
         Environment: Ubuntu linux 8.10 IA32
            Reporter: Dingwen Yuan


I have run the lusearch with GenCopy production build for two times(two invocations with each one run). The maximum heap size is 60M. The first time the benchmark passed without problem. But for the second time, the benchmark hangs without any error message. I suspect the problem may have something to do with GenCopy.

The following is the trace:
