      Description

      Red Hat Enterprise Linux box hangs (becomes inaccessible) when ParallelGCThreads in Sun JVM are higher than # of CPUs within Cpuset. Cpusets were to map individual processes to logical, hierarchical groupings of CPUs and units of memory.

           Java process 1: CPU id 1 to CPU id 7.
                Process 2: CPU id 8 to CPU id 15.
                Process 3: CPU id 16 to CPU id 23.
                Process 4: CPU id 1 to CPU id 23.
                Other 8 processes are using CPU id 1 to CPU id 23.
                Total Number of processes running on the server: 12.
                Changed Parallel GC Threads for all processes to 24.
