Thanks for bringing this up. We need to update Cheroot in Fedora and EPEL 8. I've opened https://src.fedoraproject.org/rpms/python-cheroot/pull-request/3 to get this into Fedora first. I've published an el8 RPM at https://fedorapeople.org/~ktdreyer/bz1868629/ for early testing. I can bring up a "hello world" cherrypy app with this, but I've not tested it with Ceph. - Ken On Mon, Dec 7, 2020 at 9:57 AM David Orman <ormandj@xxxxxxxxxxxx> wrote: > > Hi, > > We have a ceph 15.2.7 deployment using cephadm under podman w/ systemd. > We've run into what we believe is: > > https://github.com/ceph/ceph-container/issues/1748 > https://tracker.ceph.com/issues/47875 > > In our case, eventually the mgr container stops emitting output/logging.
