I regularly see memory leaks in ovirt-ha-agent and vdsmd. For example, I have a two-node 4.2.0 test setup with a hosted engine on iSCSI. Right now, vdsmd on one node is using 7.8G RAM, and ovirt-ha-agent is using 1.1G on each node. I've had this kind of problem with 4.1 production systems as well; it just seems to be a recurring issue. I have to periodically go through and restart these services on the nodes. Occasionally I see sanlock use up a bunch of RAM as well. -- Chris Adams <cma(a)cmadams.net&gt;
