Ken Dreyer (Red Hat) 2016-12-07 21:21:21 UTC Summary Backport: http://tracker.ceph.com/issues/14120 : Pipe::do_recv() may loop infinitely OSD SimpleMessenger thread gets stuck in a loop and burns CPU
Ken Dreyer (Red Hat) 2016-12-07 21:45:07 UTC Doc Text Cause: The Ceph OSD messenger thread could enter an indefinite loop in some scenarios where the network is interrupted between Ceph clients and OSDs.

Consequence: As a consequence, OSDs could use consume CPU and become unresponsive, and cluster service could be degraded.

Fix: The OSD code has been altered to avoid infinitely looping in this scenario.

Result: OSDs are more resilient to scenarios that trigger this bug.
