The questions are: How much main memory do you have, what is git trying to cram into it, is there a way to reduce the memory footprint or do you need to add more RAM? > any recommendations on how to pin point the "offender"? ;) Running "GIT_TRACE=1 git pull --ff-only origin master" would be a good start, I think, to find out which of the different activities that pull is doing causes the out-of-memory error. "free" and "ulimit -a" can help you find out how much memory you can use. Also: What does "wc -L .git/FETCH_HEAD .git/packed-refs" report? getdelim() is used mostly to read lines from files like these and in the admittedly unlikely case that they are *really* long such an error would be expected.
