Yum upgrade cant allocate memory

[Master of Reality]

So my second attempt at a Yum upgrade after moving my var directory to my other HD to make room for all the dled packages and whatnot.

I get this error about 48 times before it segfaults.

Updating : libgomp ################### [ 48/2115]
error: Couldn't fork %post: Cannot allocate memory
zsh: 13024 segmentation fault yum -y update

any ideas how to solve this one, I havent found much info searching around.
