[CentOS-mirror] Problems with max clients being reached

I have been trying to sync our mirror from msync.centos.org and consistently receive max connections errors. Since this seems to be the case for days on end, my mirror never gets a chance to sync.

Is there a way to find out when there are times of low connections so I can choose a time that will allow me to connect? I know that if someone tells me a particular time, a whole bunch of other mirror admins will probably jump on that same time, which would be pointless. So, it would be nice to be able to see a graph with the number of connections over time to make an informed decision when this happens.

I've also tried to use us-msync.centos.org, but have not had any better results.

Thanks, Stuart
