Using various builds of JDK 1.4.1 (builds 15-21) on an 8x900Mhz V880,
one or more JVM instances (we use 4 instances of BEA weblogic 7.0)
will terminate intermittantly with either SIGSEGV or SIGBUS at
elevated loads. The problem has been reproduced on 2 different
V880 machines running the benchmark.

JDK 1.4.0 does not exhibit this behavior.

The options used are:

-server -XX:+AggressiveHeap -Xmx2500m -Xms2500m -Xmn300m -XX:MaxTenuringThreshold=3 -XX:SurvivorRatio=20

Currently testing with "-XX:-InlineArrayCopy" option.
