Depending on what is going on the first heartbeat can occur anytime during the first 5 minute interval, so that is not too surprising. > > > The workaround is either to turn off heartbeat in your FD for your Verify > > jobs (not possible on a job by job basis) or set it longer than the time > > it takes to run the verify. By the way, when using your localhost loopback device, you should never need to enable heartbeat. It is needed only when you have a router between two machines and that router does not correctly implement the Internet keepalive standard. > > There are some very long running verify jobs (TB's of data), setting > the heartbeat to an interval of xx hours wouldn't make sense.
