It looks like pushing so many patches in one go triggered Gerrit and git to
consume large amounts of memory. This lead to Gerrit being OOM killed. It looks
like we don't have an swap space on this box. I've just added 1G of swap to
reduce a chance this happens next time.

Yaniv, can you try pushing again?
