RE: Error Fetching http headers
We have an intranet with a page that retrieves sales orders from NetSuite for viewing by our customer service team. This page makes 5 SOAP calls to get all of the information of for the order. This includes the order details, notes, item tracking, etc.
We have one user that frequently gets a blank screen and, through some troubleshooting code, we can see that the requests are failing with the error “Error Fetching http headers”. This started happening a few months ago with a different order import integration program that also uses SOAP calls and we able to mitigate that by re-instantiating the connection service just before the SOAP call as it seemed they were timing out. But that seems to not have helped with our intranet page.
Any ideas on what could be causing this or how to correct it?
Depending on how many integrations you have using SOAP(SuiteTalk) you may be hitting Concurrency Limits.
While this does not address your problem directly I will suggest you consider moving your Intranet integration to use a Restlet(I would try to move everything I can to Restlets because SOAP is such an old and slow protocol I will avoid to use every single time.)
Just by moving this to a Restlet you automatically go from 5 calls to just 1.
