PR - memory leak in lua

Hi,

I think this is quite important, I will be glad if you will have time to look at it.

Discovered when developing this module GitHub - tivvit/aerospike-bloom-filter: Bloom filter UDF module for aerospike DB

Thanks for the pull request. We’re looking into the memory leak now.

Hi, do you have any problems with reproducing the leak? May I help you somehow?
