Woops, my mistake. I think I multiplied by 1024 extra. Mbuf's are 2KB's, not 2 MB's (that's the huge page size)
But the fact remains that my usecase is unstable at higher configured buffers but is stable at lower values like 100000 (this can by all means be my usecase/code specific issue) If anybody else facing issues with higher configured buffers, please do share.
