OK.  I have a question.

Your video directory (as configured non-storage group)...  does it
have any symlinks in it that would possibly cause a cycle...  or do
you have many many files?   It seems you are in an infinite loop
filling memory.

This is not normal :)

If you are not sure what I mean...  then do:

find /data2 -type l > /tmp/data2.txt

And then check each of the reported links.  If any of them are -> . or
-> .. or the like, that could be a serious issue.
