Thanks Konstantin.

Previous allocation error was coming with 1024 huge pages of 2 MB size. 

After increasing the huge pages to 2048, I was able to add another ~140 rules [IPv4 rule data--> with src, dst IP address & port, next header ] more, ie., 950 rules were added.

Logically it did not increase number of rules [expected 2*817, but only 950 were added]. Is it really using huge pages memory only? 

>From the code it looks like heap memory. [ ret = malloc_heap_alloc(&mcfg->malloc_heaps[i], type, size, 0, align == 0 ? 1 : align, 0) ]

You are running out of hugepages memory.
