(Note: I am not a networking engineer) We are sending files to an outside vendor and getting random timeouts on different services. It seems that we are getting timeouts most often on larger files. We did a packet capture that shows our window shrinking and suspect that the small payloads make it before the window hits 0, where large payloads give us a RST.

Edit: I'm referring to different web-services that we are calling from our application. The timeouts don't consistently fail on a specific service, but instead hit all the services at different times. I cannot send it from a different network.

What does this mean:getting random timeouts on different services
? What do you mean bydifferent services
? Do you mean different file transfer methods?2.
Have you tried sending the files from a different network? If so, do you get the same results?
