Lua scripts leak memory

[dmknght]

I found your conky and i edited your configuration files a little bit. After few days, i found that lua scripts randomly leaked my ram (more than 1Gb ram, but conky processes used 30~40Mb ram only). I tried to add cairo_destroy(cr) to scripts but I could not fix it. I am using Parrot OS 3.10, based Debian 10 testing.
