IPASCII Response fails every other poll.

Question

IPASCII Driver object is used to retrieve (via Ethernet) data.
Request format works good.
My Request Format (RequestFormat):
"GET /data HTTP/1.0 \r\n\r\n" as per device manufacture Txt string and
(2) carriage return/line feeds
Response String looks good Object = (.Response)
Typical Response String
F|74.0|29.3|-999.9|74.0|29.3|-999.9|-999.9|-999.9|-999.9|-999.9|-999.9
|-999.9
Data is temperature from module, -999.9 are data inputs without temperature
probes attached...
RSV1.txt = (F)
RSV2.txt = (74.0)
ETC...
RSV1-13 data look good but fails every other poll
(Socket communications error 10053: Software caused connection abort).

Answer 1

I have received the following response from NI engineers.
To review this issue -- the IPASCII object has a problem in that if you use the IPASCII object to query a web service that closes the
connection remotely after a request has been made Lookout will not close the local connection.  This results in a "CLOSE_WAIT"
state for the local TCP port.   Since the port is not closed, Lookout is not able to make a subsequent outgoing connection on the
same port.  Lookout does appear to close the port when after it tries to make repeated connections, but this means for every time
you want to make a query you have to alternate between successful queries and comm failures. Most likely this was not found earlier
because for many Ethernet based instruments, a TCP connection is persistent, however web servers using the HTTP/1.0 protocol
close the TCP connection after every GET request and response.  A corrective action request has been filed with our Lookout R&D
team and hopefully a fix will be available in future versions of Lookout.  Thank you for your patience with this issue.
