I tried running the test PMD. It takes 64G VSZ and if I use the '--in-memory' option it takes up to 188G. Is there anyway to disable allocation of such huge VSZ in DPDK ? This is resulting in huge core files and I suspect that the problem will compound on multi-NUMA machines. Please help Regards, Siddarth
