Ok, the hosts seems to be online again, but it took quite a long time.. Am 08.05.2023 um 13:22 schrieb Mevludin Blazevic:

Hi all,

after I performed a minor RHEL  package upgrade (8.7 -> 8.7) in one of our Ceph hosts, I get a Ceph warning describing that cephadm "Can't communicate with remote host `...`, possibly because python3 is not installed there: [Errno 12] Cannot allocate memory, although Python3 is installed. However, I figured out that these packages were updated:

Is something odd with the updated Python3 packages?
