I have seen vdsmd leak memory for years (I've been running oVirt since version 3.5), but never been able to nail it down. I've upgraded a cluster to oVirt 4.4.9 (reloading the hosts with CentOS 8-stream), and I still see it happen. One host in the cluster, which has been up 8 days, has vdsmd with 4.3 GB resident memory. On a couple of other hosts, it's around half a gigabyte. In the past, it seemed more likely to happen on the hosted engine hosts and/or the SPM host... but the host with the 4.3 GB vdsmd is not either of those. I'm not sure what I do that would make my setup "special" compared to others; I loaded a pretty minimal install of CentOS 8-stream, with the only extra thing being I add the core parts of the Dell PowerEdge OpenManage tools (so I can get remote SNMP hardware monitoring). When I run "pmap $(pidof -x vdsmd)", the bulk of the RAM use is a single anonymous block (which I'm guessing is just the python general memory allocator). I thought maybe the switch to CentOS 8 and python 3 might clear something up, but obviously not. Any ideas? -- Chris Adams <cma@cmadams.net>
