Open Feign uploading multipart file fails with OOM. File only 287MB

[andreainfogix]

Hello,

When uploading a multipart file via a feign client, the OOM is raised with the following stack. File zipped in bz2 format required by the server with only 287MB. I know some people experienced this issue with larger files. Did anyone find a solution to overcome this? thanks
