Run in the end of init file

collectgarbage()
LOG(gcinfo())
LOG("AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA")
a = {}
for i = 1, 10000 do
    a[i] = setmetatable({}, { __mode = "v" })
end
collectgarbage()
LOG(gcinfo())
a = nil
collectgarbage()
LOG(gcinfo())

Note:

gcinfo returns two results: the number of Kbytes of dynamic memory that Lua is using and the current garbage collector threshold (also in Kbytes).
