1.8.7 High CPU load on multisite Ceph Object Gateway nodes

Ceph Object Gateway multisite configurations make significant use of curl functions such as curl_multi_wait(). A deadlock issue existed in earlier versions of the curl library, but was fixed in version 7.31 and later.

Oracle has backported the patch to fix this issue in curl version 7.29.0-25.0.2. This fix is available in the latest errata release of Oracle Linux 7.

If this problem occurs, make sure that you have the latest version of the curl and libcurl packages installed from the ol7_latest and ol7_optional_latest repositories.
