pthread_create fails with error code 11 (pthread_create: Cannot allocate memory)

I am running dpdk with my existing application and after rte_eal_init, other inits and rte_eal_remote_launch, It end up going through my existing app that starts some more threads.

I do see all the rte_* ran successfully. But the pthread_create calls from my existing app fails with the following logs,

VMM rlimit set to 16000000000
pthread_create: Cannot allocate memory
pthread_create: 11
movik_terminate called - program will exit


I have hugetables set up. I tried reducing the stack using ulimit -s 1024 and I still see the same issue.

Any idea?
