>> Area batch run out of memory error
>> When generating an area run, you may receive the following:
>> Query run out of memory in "recurse" at line 255 using about 1157 MB
>> (Assuming you have enough physical free memory, 4gb worked for me) Try removing all the "area" files from your database directory and increase the element-limit (in your $DB_DIR/rules/rules.osm3s file) to "2073741824"

>> http://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Element_limit_.28maxsize.29
>> Element limit (maxsize)
>> The maxsize setting has one parameter, a non-negative integer. Default value is 536870912 (512 MB).
>> This parameter indicates the maximum allowed memory for the query in bytes RAM on the server, as expected by the user.
