The heap size is too low. The max you can get on x86 is 1024 on windows.
How much memory is in the box? how many instances are they running?
You can change the max heap in the infrastructure manager gui, edit the appserver instance.
Changing the xmx setting in the registry only changes the heap of the launcher.
hi Bill thanks for the suggestion, we will adjust the heap setting to 1024M and monitor performance. I will post up the results.
You can actually go to 1536 on Windows x86 as a max .. Make sure your system has enough memory as JVM wants a contiguous block of the system's available memory.
