I confirm that we occasionally see "weird" issues on hugemem kernels
with "our" AFS on a test machine - typically file content looks like
every char is replaced by a 16bit entity (which  occasionally gets
misinterpreted as UTF by the applications). Since nobody seems to be
using that kernel at CERN, we haven't investigated any further so far..
(and we just recompile the modules for hugemem since that is done by a
script).

And yes, you should not be using SLC45 (unless you have applied all
updates, in which case this would be equivalent to SLC47).
