Hi, I've always had some MGR stability issues with daemons crashing at random times, but since the upgrade to 14.2.8 they regularly stop responding after some time until I restart them (which I have to do at least once a day). I noticed right after the upgrade that the prometheus module was entirely unresponsive and ceph fs status took about half a minute to return. Once all the cluster chatter had settled and the PGs had been rebalanced (auto-scale was messing with PGs after the upgarde), it became usable again, but everything's still slower than before. Prometheus takes several seconds to list metrics, ceph fs status takes about 1-2 seconds. However, after some time, MGRs stop responding and are kicked from the list of standbys. With log level 5 all they are writing to the log files is this: 2020-03-11 09:30:40.539 7f8f88984700 4 mgr[prometheus] ::ffff:xxx.xxx.xxx.xxx - - [11/Mar/2020:09:30:40] "GET /metrics HTTP/1.1" 200 - "" "Prometheus/2.15.2" 2020-03-11 09:30:41.371 7f8f9ee62700 4 mgr send_beacon standby 2020-03-11 09:30:43.392 7f8f9ee62700 4 mgr send_beacon standby 2020-03-11 09:30:45.412 7f8f9ee62700 4 mgr send_beacon standby 2020-03-11 09:30:47.436 7f8f9ee62700 4 mgr send_beacon standby 2020-03-11 09:30:49.460 7f8f9ee62700 4 mgr send_beacon standby I have seen another email on this list complaining about slow ceph fs status, I believe this issue is connected. Besides the standard always-on modules I have enabled the prometheus, dashboard, and telemetry modules. Best Janek
