Hi Bhanu,
Can you tell me a bit more about your scenario and how many CPUs
you're dealing with? Is it an offload EM or non-offload EM that's
running out of resources?
The (non-offload) EM starts with 4k XIDs. It must be an extreme case if
it is running out of per-CPU XIDs. Especially if you're failing
discovery, when there shouldn't be that many exchanges in use.

I'm not sure the offload EM would want this common pool since the OEM
may have a much smaller set of XIDs.
