Sun GlassFish Communications Server 1.5 Release Notes

Communications Server wrongly reports CPU usage when using only one of the cores of a multi-core system (Issue 1344)


On Solaris platforms, Communications Server calculates CPU usage based on the number of available processors and the per-core CPU usage. However, Communications Server takes into account the static value of number of cores and not the number of cores that are used by the JVM.


Recalculate the CPU threshold values if you are not using all the cores in the machine.
