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 ?

As you mentioned above timeout would be a potential cause of context been cancels. However we would better make sure the harbor running healthily and then collect both the server and the client log to traige it case by case when you are able to reproduce it.

And we will keep traige this issue on it #15751
