TCP communication temporarily dies

Hi There

 

Im using TCP to communicate between my ARM processor and PC. However, the communication sporadically dies for 3 to 4 seconds and then resumes, as shown in the Task Manager Networking (attachment 1) . This happens with the simplest of test programs, as shown in the attachments, and no delays or sequences seemed to solve the issue. 

 

After some duration the communication dies completely with error code 66.

 

What is causing the delays in communication and is there a fix for this?

Hey,

 

What kind of delay did you add into the VI?  it sounds like a pretty classic case of reading and writing TCP too fast.  You may want to take a look at this article: http://digital.ni.com/public.nsf/allkb/4CB799F36D0EA56A862576200064B2F9?OpenDocument
