Public bug reported: This is to track and SRU the upstream bug [0]. In large clusers, there's a GIL deadlock that happens (or observable) when ceph-mgr receive high number of requests from Prometheus module.
This bug likely exists at least since the initial release of Nautilus. Upstream fixed this recently [2]. Targetted for Octopus 15.2.9 (which is not released yet - the next point release). So this tracker is to assess the impact and potentially backport in Ubuntu/UCA packages before 15.2.9 gets released. N.B: We have previously backported a similar bug [1]. But this is unrelated.
