This was the fix I was thinking of as well. Not sure if there are other
potential IO exceptions that should have different behavior though. Thanks for
such quick turnaround! Do you know when 14 will be released?

> Connection aborted infinite loop

> Key: HTTPCORE-647
> URL: https://issues.apache.org/jira/browse/HTTPCORE-647
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Affects Versions: 4.4.13
> Environment: java 8
> Reporter: Lukas O'Daniel
> Priority: Major
> Fix For: 4.4.14
>
> Attachments: Client.java, Entity.java, Server.java
>
>
> There is some issue that occurs when a response is not fully written and the
> connection closes or times out in 4.4.13. When this occurs, there is some
> infinite loop that logs the stack trace multiple times per millisecond. I
> have attached a simple example that can reproduce this behavior. The entity
> I'm using is based on NByteArrayEntity. In practice this issue was extremely
> rare on our servers, but requires restart to fix.
>
> This can be reproduced by running [^Server.java] and then running
> [^Client.java]

> For localhost I get the error and stack trace dumped infinitely:

> I was getting the equivalent on remote hosts with different error message:
> \{{ java.io.IOException: An existing connection was forcibly closed by the
> remote host}}
>
> Apologies for formatting, etc this is my first open source bug report.
> This seems like it could be related to the fix for HTTPCORE-607. I don't get
> this issue, at least for this example code, using 4.4.12 and previous.
