Hi, During testing (mimicking BGP / port flaps) on our cluster we are able to trigger a "_committed_osd_maps shutdown OSD via async signal" on the the affected OSD servers in that datacenter (OSDs in that DC become intermittent isolated from their peers). Result is that all OSD processes stop. Is this a bug or a feature? I.e. is there a "flap" detection mechanism in Ceph OSD? If it's a bug it might be related to http://tracker.ceph.com/issues/20174. We get similiar error message on "12.2.0". Version "12.2.1" does not log "-1 Fail to open '/proc/0/cmdline' error = (2) No such file or directory -1 received signal: Interrupt from PID: 0 task name: <unknown> UID: 0 -1 osd.21 1846 *** Got signal Interrupt *** 0 osd.21 1846 prepare_to_stop starting shutdown -1 osd.21 1846 shutdown" Gr.
