Hi, [mon] mon initial members = a [mon.a] mon addr = 192.168.0.1:7000 jewel release with 1 monitor and 3 OSDs. After hours of fio rbd test, the monitor binded port(7000) was closed for unknown reason. But monitor is still running, # pidof ceph-mon 21980 Another strange thing is there are more than 1000 threads for the ceph-mon process. # ls /proc/21980/task/ |wc -l 1022 Any possible reason?
