The log output you pasted suggests that an oom killer is responsible
for the failure, can you confirm that? Are other services located on
that node that use too much RAM?

Hi Guys,
I am in the upgrade proccess from mimic to nautilus.
The first step was to upgrade one cephmon, but after that this
cephmon can not rejoin the cluster I see this at logs:
2022-06-29 15:54:48.200 7fd3d015f1c0 0 ceph version 14.2.22
(ca74598065096e6fcbd8433c8779a2be0c889351) nautilus (stable),
process ceph-mon, pid 6121
2022-06-29 15:54:48.206 7fd3d015f1c0 0 pidfile_write: ignore empty --pid-file
2022-06-29 15:54:48.339 7fd3d015f1c0 0 load: jerasure load: lrc load: isa
This machine is mon and mrg and the mgr daemon y working fine after upgrade
At log messajes:
