To reduce load, download.fedora.redhat.com (official host) contains the ~1kB checksum for the metadata. The metadata (usually ~1 – 2 MB) is downloaded off mirrors. After downloading metadata, Yum compares the two to make sure they're one and the same.
Now, think of this: download.fedora.redhat.com updates their metadata and checksums, so you're getting the new checksum. The mirror's cronjobs havn't gone yet, therefore no synching and the metadata isn't the newest, it doesn't match.<\/p>\n

The solution is not to makecache; Although it may help it will take forever and still not 100% solve the problem. The main problem is not giving the mirrors enough synch time. Typically, cron runs every hour, and give it a bit of time to download the changes, so I'd say try running maybe 10 minutes after an hour and you'll have no problem (eg 3:10, 4:10, 5:10, etc…). If you get closer to :50 (3:50, :50, etc) you'll start seeing more syncing issues.<\/p>\n

Again, this too isn't 100% perfect but more of a guideline. There's a lot of guesswork…<\/p>\n
