Hello All,

We are running WAS 6.0.2.17 64bits in Windows Server 2003 x64. We have a default core groupe (4 JVMs) with a replication domain for the DynamicCache, and for all JVMs in this Core Group.
When the Ripple Start is beginning, this error occurs and the CPU usage for each running JVM is around 25%! I need to restart all JVM to stop this big CPU usage.
