Are you opening and closing connections for every request, or using a connection pool/persistent connections? I'm not using LuaSQL in production but have done load testing at 1000's of queries per second with no issue using persistent connections (catching and re-opening connections closed by MySQL as idle).

After somewhere between 1500-2000 queries to the database (this is in a 20-30 minute period), the driver hits this error in the code:

 /* Try to init the connection object. */
 conn = mysql_init(NULL);
 if (conn == NULL)
   return luasql_faildirect(L, "error connecting: Out of memory.");
