I have a soap request I want to test. Its size is about 35kb, not tiny but also not huge by any means. However when I send it to the server, the server only receives a part of it, and then keeps waiting. SoapUI keeps waiting too and eventually timeouts.
When I try the same with curl, both locally (on the VM I'm running the server on), and remotely (still on my machine but not on the VM), it just works: the server receives the complete request and SoapUI receives the answer.
I can make the request smaller by removing some data I don't really need for this test and by using namespace aliases instead of repeating them all over, and this eventually works when I get the request small enough. So I have a workaround but since I can't seem to find any tools that automatically alias as many namespaces as possible this is very labor intensive so I'd rather avoid it.
This may be the solution. There is a default size of raw request and response of 10000 that can be changed. Look in your UI preferences and update the size limit. I dont have anything I can test it out with but this might help
