this usually happens when looking on the console log and has no affect on
the jobs itself(a refresh solves it)
maybe has to do with the proxy time out parameters in apache vhost
increased proxy timeout https://gerrit.ovirt.org/59970, keeping this ticket for tracking.
please check if still relevant, if not please close,
do you know if this is still relevant?
Can be closed, looks like the apache fix resolved it(at least didn't get any complaints about it)
