The most common cause of the routing loops is the misconfiguration of the routing protocols/parameters on the router.

hi
one of the major cause of a routing loops is a redistribution from one protocol into another,especialy when you have two boundary routers both of them doing redistribution .
if it s not planned adequately you can create a feed back hence a loop!!!
HTH
please do rate if it does clarify

I believe the most common cause is incorrect config on the default route / static route.
For example, two routers that have each other as the default gateway. If a packet arrives destined to an unknown subnet, the routers will send the packet back & forth until it times out (TTL expired).
OR one router with a Default to another router (and maybe others .... ) where one has a static back to the router with the default
Good Luck
