I know that was my mistake.

My problem is why the openafs modules consumed all the free RAM on
the client?  Don't the openafs client or the modules have protections
in place to prevent following infinity cycles in the path?

Can it be possible for a normal user to create this kind of infinity
cycles in the path?  And this way to cause a DoS on a multi-user
server that is client of AFS?
