Tim Taylor commented on PROTON-2347:
------------------------------------
My apologies for the duplicate issues that I filed. The Jira GUI displayed some
odd exceptions when I tried to file the first few issues, so I thought they
weren't created.
> Reactor leaks file handles when an IO Exception is encountered
> --------------------------------------------------------------
>
> Key: PROTON-2347
> URL: https://issues.apache.org/jira/browse/PROTON-2347
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-j
> Affects Versions: proton-j-0.33.8
> Environment: Windows 10 desktop
> Reporter: Tim Taylor
> Priority: Minor
> Fix For: proton-j-future
>
> Attachments: repro.txt
>
>
> When I try to open a connection using proton-j while my machine doesn't have
> internet access, I see that proton-j leaks file descriptors. Attached is the
> sample I wrote that repro's this issue. I'm looking either for guidance on
> how to handle IOExceptions in the onTransportError callback, or for a
> confirmation that what I'm doing to handle them is correct, and that there is
> a bug in proton-j around this scenario.
>
> If you need help viewing the file descriptor count growing over time, the
> [process explorer
> tool|https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer]
> is what I've been using. Running the sample in a loop will make this leak
> more obvious, but it isn't required to leak the file descriptors. This same
> bug seems to happen in Linux and MacOS as well.
