Hi Dafna, I've just merged https://gerrit.ovirt.org/99339 which adds missing debug logs for BLL part of engine, which contains core functionality. So hopefully now we should have finally all debug info to be able to investigate a fix all race/random issues we have in the last weeks. Regarding the GetVdsHooksByIdQuery I think Marcin started to investigate and the issue was that for some unknown reason hooks are not stored within engine database, which seems like a race between hooks are queried from client and properly fetched from host withing HostMonitoring. So next time it happens we should hopefully have enough information to be able to find out reason. Thanks M.
