Description Steven Haigh 2016-08-17 02:08:50 UTC
Description of problem:
When running a C# program that waits for events, the DotNet core application waits for input while the underlying libcurl event gets stuck in a loop.

This causes the application to use 100% cpu usage.

Affected Components:
libcurl.x86_64 7.29.0-25.sl7

This has been reported to the dotnet core github Issues:
    https://github.com/dotnet/corefx/issues/9751

A possible fix was identified in libcurl 7.32.0. The commit reference is:
    https://github.com/curl/curl/commit/6d30f8ebed34e7276c2a59ee20d466bff17fee56

This issue does not occur to distributions using libcurl versions 7.32.0 or beyond.

I'm not sure exactly what the official policy is for backport requests - or if this is the only commit required to fix this issue with DotNet Core vs libcurl - however am willing to test packages in our environment to verify / validate any fixes.

Sorry, I meant RHEL-7.3.  Thanks to Ken Dreyer for making me aware of the typo!
