[Bug 1868716] Re: git: fatal: mmap failed: Cannot allocate memory

[Dimitri John Ledkov]

can you please first do:

$ git remote update
(that will try to download all the things without reconciling your tree)

$ git repack

$ git clean -f -x -d
$ git clean -f -X -d

Then

$ git pull

It is known that on very large trees, with many dirty changes things
don't work in a single go.
