Request with large files to netflix-zuul, will be routed to eureka-client without files - spring-boot

Question

When sending Requests that contain large files(850MB) to netflix-zuul, the request is routed to the client but the file in the request will be null.
It works properly when sending a request with small files(10Mb).
Other params received successfully on both requests.
The request is sent to /zuul/uploadFile because of the large file.
Send request chunk or without chunk header but not working.
Change rest endpoint Multipart to MultipartHttpServletRequest but not working.
Increase the timeouts but not working.
netflix-zuul application.yml like
spring:
context-path: /api
http:
multipart:
maxFileSize: 1048576KB
maxRequestSize: 1048576KB
....

Client rest controller
#RestController
#RequestMapping(value = "/uploadFile")
public class uploadFileController {
#RequestMapping(method = RequestMethod.POST)
public ResponseEntity<UploadResponse> create(#RequestParam(value = "file") MultipartFile[] files,
UploadFileModel uploadFile,
#RequestHeader(value = "userInfo", required = false)
final String username) {
ResponseEntity.accepted().body(new UploadResponse());
}
Request as mentioned in the document:
(mozilla said that Transfer-Encoding is for response Header. I am not sure that is curl correct.
curl -v -H "Transfer-Encoding: chunked" -F "file=#uploadingFiles.zip" http://localhost:8081/api/zuul/uploadFile/
Response something like :
* Connected to localhost (::1) port 8081 (#0)
> POST /api/zuul/uploadFiles/ HTTP/1.1
> Host: localhost:8081
> User-Agent: curl/7.54.0
> Accept: */*
> Transfer-Encoding: chunked
> Expect: 100-continue
> Content-Type: multipart/form-data; boundary=------------------------1b39649403c702d0

Also, after sending the request with large files, i will try to send another request (some GET request) to same client and i get error from netflix-zuul

Answer 1

I find out that the reason is that not enough heap size. I think that files will be corrupted if heap size is not enough but zuul still dispatch the request.
Spring web can not parse multipart files because not found separators in the data and set as null.
