-----------------------------------------------
[~philippn] I am not sure what it is exactly you expect us to investigate.
Connection resets (with very few exceptions) is a server side issue.

> Key: HTTPCLIENT-2081

> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic)
> Affects Versions: 4.5.12
> Reporter: Philipp Nanz
> Priority: Major
> Attachments: connection-reset.txt

> Hi there,
> we are currently using HttpClient for downloading blobs off IBM COS, which is
> basically a S3-like cloud storage.
> Sometimes we are seeing that HttpClient is giving up with "connection reset"
> errors after doing its retries.
> A quick Jira search showed that there were similar issues reported recently,
> but not investigated further (HTTPCLIENT-1954, HTTPCLIENT-2049).
> I have attached a log file including the full wire protocol.
> There is a couple of things that seems fishy: first of all, there is a read
> timeout being reported after 3 ms or so. On the subsequent retries, I suspect
> that the same connection is being reused and hence the peer sends the RST
> packets. But that is just my wild speculation, because I cannot read much
> from these logs.
> Since this is happening only ocassionally, I'm guessing at a timing related
> issue. Hence, my next step is to tweak the retry handler in a way that it
> waits for a small amount of time. I will report back my findings.
> If there is anything else you need, please let me know. I will be happy to
> provide anything that is necessary to further invbestigate this issue.
