4am is the point time the standard cron-jobs (makewhatis, updatedb etc)
are being launched. So it's very likely it might be related to them.

My "usual suspects" would be 
* rpmdb corruption (I once had a case something related to rpm hung each
night at 4am)
* networking issues (updatedb trying to recurse into stale nfs-mounted
file systems).
* yum-updatesd.
* some cron-job related job running out of diskspace.
