The following bug occurrs because of the following query being run from GetVmStatsVDSCommand every running VM in the system. The run is cyclic and runs in infinitive loop. I don't see reason of that query, update of dynamic data ofor disc is done under lock, in worst case the dynamic data will be updated with wrong values, in next run which occurring every 4 seconds, the disk will be updated with correct values. I think we can live with wrong values for 4 seconds in case of race The change reduced CPU of machine with DB from 100% to 30%, which is still a high, but better Change-Id: I9ef4a24908a75ab4fc1f02eed7c97a7125a5db41 Bug-Url: https://bugzilla.redhat.com/879930 Signed-off-by: Michael Kublin <mkublin(a)redhat.com&gt; --- M backend/manager/modules/vdsbroker/src/main/java/org/ovirt/engine/core/vdsbroker/vdsbroker/VdsBrokerObjectsBuilder.java 1 file changed, 22 insertions(+), 37 deletions(-) Approvals: Michael Kublin: Verified; Looks good to me, approved -- To view, visit http://gerrit.ovirt.org/9468 To unsubscribe, visit http://gerrit.ovirt.org/settings Gerrit-MessageType: merged Gerrit-Change-Id: I9ef4a24908a75ab4fc1f02eed7c97a7125a5db41 Gerrit-PatchSet: 2 Gerrit-Project: ovirt-engine Gerrit-Branch: master Gerrit-Owner: Michael Kublin <mkublin(a)redhat.com&gt; Gerrit-Reviewer: Allon Mureinik <amureini(a)redhat.com&gt; Gerrit-Reviewer: Michael Kublin <mkublin(a)redhat.com&gt; Gerrit-Reviewer: Michal Skrivanek <michal.skrivanek(a)redhat.com&gt; Gerrit-Reviewer: Omer Frenkel <ofrenkel(a)redhat.com&gt; Gerrit-Reviewer: Yair Zaslavsky <yzaslavs(a)redhat.com&gt;
