Harbor sometimes returns 500 when pushing images

[Pavan-Gunda]

Hi,

We sometimes see harbor returning an internal server error 500 when pushing images.

level=fatal msg="writing blob: uploading layer to https://harbor.xxx.com received unexpected HTTP status: 500 Internal Server Error"

In harbor core, the error message is "Handler crashed with error net/http: abort Handler"

I searched through the issues related to this and found these,
#15751
golang/go#4074
#19323
#17908

And also increased the proxy timeouts as suggested in here. Any thoughts as to why this could happen and what else i should look for ?
