Hi Yehuda,
Well, again, thank you!
I was able to get a package built from the latest curl release, and after upgrading on my radosgw hosts, the load is no longer running high. The load is just sitting at almost nothing and I only see the radosgw process using CPU when it is actually doing something now.
So, I am still curious if this would be considered a bug or not, since the curl version from the base CentOS repo seems to have an issue.
Have a good day,
Lewis George

Hi Yehuda,
Thank you for the idea. I will try to test that and see if it helps.
If that is the case, would that be considered a bug with radosgw? I ask because, that version of curl seems to be what is currently standard on RHEL/CentOS 7 (fully updated). I will have to either compile it or search 3rd-party repos for newer version, which is not usually something that is great.
Have a good day,
Lewis George

We've seen that happening when running on a system with older version
of libcurl (e.g., 7.29). If that's the case upgrading to a newer
version should fix it for you.
