We have an integration that uses the SOAP api to push sales orders into our NetSuite system. This has worked well for us in a number of integrations that we have done. We just created a new that imports 50 to 100 orders at a time. (each is created with an individual SOAP call but they run consecutively as the program iterates through an import file). The problem is that we are getting occasional "Error Fetching http headers" errors. The orders that fail subsequently import correctly when retried without any modification to the order. Any ideas?
