To be exact I did the clone locally on the same machine and so the clone itself worked
but I got the OOM during the first fetch. I "fixed" this by setting transfer.unpacklimit=100000
which caused only loose objects to be transfered. 
So in this case I think the OOM was on the remote side. But there is another OOM if I try to repack locally.
It seems to me that neither pack-objects nor index-pack respekt pack.packsizelimit and always
try to pack all objects to be transferred resp. all local loose objects in one pack.
I could live wth the transfer.unpacklimit=100000 but the local OOM stops me from using the cloned repo.
