Hi, yesterday we changed RGW from civetweb to beast and at 04:02 RGW stopped working; we had to restart it in the morning. In one rgw log for previous day we can see: 2023-10-06T04:02:01.105+0200 7fb71d45d700 -1 received signal: Hangup from killall -q -1 ceph-mon ceph-mgr ceph-mds ceph-osd ceph-fuse radosgw rbd-mirror cephfs-mirror (PID: 3202663) UID: 0 and in the next day log we can see: 2023-10-06T04:02:01.133+0200 7fb71d45d700 -1 received signal: Hangup from (PID: 3202664) UID: 0 and after that no requests came. We had to restart rgw. In ceph.conf we have something like [client.radosgw.ctplmon2] host = ctplmon2 log_file = /var/log/ceph/client.radosgw.ctplmon2.log rgw_dns_name = ctplmon2 rgw_frontends = "beast ssl_endpoint=0.0.0.0:4443 ssl_certificate=..." rgw_max_put_param_size = 15728640 We assume it has something to do with logrotate. /etc/logrotate.d/ceph: /var/log/ceph/*.log { rotate 90 daily compress sharedscripts postrotate killall -q -1 ceph-mon ceph-mgr ceph-mds ceph-osd ceph-fuse radosgw rbd-mirror cephfs-mirror || pkill -1 -x "ceph-mon|ceph-mgr|ceph-mds|ceph-osd|ceph-fuse|radosgw|rbd-mirror|cephfs-mirror" || true endscript missingok notifempty su root ceph } ceph version 16.2.14 (238ba602515df21ea7ffc75c88db29f9e5ef12c9) pacific (stable) And ideas why this happend? Kind regards, Rok
