I think we may be able to do better for this. for multipart files in springboot & jetty, it should use streaming mode to not directly load the whole file in memory. But according to spring boot's documentation: https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/autoconfigure/web/servlet/MultipartProperties.html `file-size-threshold specifies the size threshold after which files will be written to disk. The default is 0.` The default is 0, so, it will parse uploaded multipart file into memory, instead of writing to temp file. So, I guess set the `spring.http.multipart.file-size-threshold` to a value like 10MB. may avoid the OutOfMemory error spring.http.multipart.file-size-threshold=10MB Can you try whether this will reduce memory usage? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
