anyone getting this error when posting to Thingspeak? should I somehow be referencing a static IP, or is it some kind of memory leak?
The code works for 20+ posts then this happens...

temperature =229375
Posted OK
Posting...
Temperature= 22.8750 Celsius
228750
temperature =228750

my code (I have an init file and another function to read an 18B20 temperature sensor as well.)

function postThingSpeak(level)
connout = nil
connout = net.createConnection(net.TCP, 0)
--184.106.153.149 thingspeak static ip
connout:on("receive", function(connout, payloadout)
if (string.find(payloadout, "Status: 200 OK") ~= nil) then
print("Posted OK");
end
end)

connout:on("connection", function(connout, payloadout)

print ("Posting...");

local volt = node.readvdd33();
t=1
gettemp(t)
print ("temperature ="..t)

connout:send("GET /update?api_key=myapi&field1=" .. (t/10000) .. "." .. (t%10000)
.. " HTTP/1.1\r\n"
.. "Host: api.thingspeak.com\r\n"
.. "Connection: close\r\n"
.. "Accept: */*\r\n"
.. "User-Agent: Mozilla/4.0 (compatible; esp8266 Lua; Windows NT 5.1)\r\n"
.. "\r\n")
end)

connout:on("disconnection", function(connout, payloadout)
connout:close();
collectgarbage();
end)

connout:connect(80,'api.thingspeak.com')
end

...I tried the Thingspeak static IP, same result..
