Yes, it is ceph pacific 16.2.11.
Is this a known issue that is fixed in a more recent pacific update? We're not ready
to move to quincy yet.
thanks,
Wyllys

Every night at midnight, our ceph-mgr daemons open up

left unchecked over days/weeks, the zombie ssh connections just keep
growing, the only way to clear them is to restart ceph-mgr services.
Any idea what is causing this or how it can be disabled?
Example:
ceph 1350387 1350373 7 Jul17 ? 01:19:39 /usr/bin/ceph-mgr -n
mgr.mon03 -f --setuser ceph --setgroup ceph --default-log-to-file=false
--default-log-to-stderr=true --default-log-stderr-prefix
ceph 1350548 1350387 0 Jul17 ? 00:00:01 ssh -C -F
/tmp/cephadm-conf-d0khggdz -i /tmp/cephadm-identity-onf2msju -o
ServerAliveInterval=7 -o ServerAliveCountMax=3 xxx(a)10.4.1.11 sudo python
[...snip...]
Is this cluster on pacific? The module in question is likely to be `cephadm`
but the cephadm ssh backend has been changed and the team assumes problems
like this no longer occur.
Hope that helps!
