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?

You are running out of hugepages memory.
