index-pack died of signal 9

Just started the course and am attempting to clone the kernel. I am running Ubuntu inside a VM set up with a 50GB drive. Git receives the objects and resolves 59% deltas before it drastically slows down. I am then left with the following which appears to overwrite the "Resolving deltas:" progress:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux_stable > build.log
Cloning into 'linux_stable'...

You could see this error due to directory permissions. Please make sure your login has permissions to write to the directory you are attempting to clone into.

I have attempted several times from my home directory and from the root directory...running with "sudo" as well.

How much memory does this VM have? Does dmesg offer any clues?

I am set up for 2Gb of memory

Did you check dmesg and other system logs for errors? This could be a memory problems. Try increasing memory for your vm

I was able to find Ubuntu was only allocating 500MB for swapfile which i have increased to 4GB. However, i don't think memory is the problem. My system appears to hang at random points in the "Resolving deltas" stage...this time at 13%. Just prior to the hang, I verified there was 3.6GB of swapfile space remaining. I am waiting for the git to fail now which usually takes 5-10 minutes of "hang time".

Nothing of note in dmesg

i never run VMs of only 2 GB when doing kernel git. i would go to 4 GB. i know that doinggit gc for example hangs a long time, even infinitely, as things are done in RAM and the repo is close to 2 GB. if you have not done so yet please try raising the memory. i've had many students do this clone without problem.

Thanks everyone. After I updated my swapfile size (correctly), I was able to get a proper git.
