Crash on large fetch

Recently Kibana had a huge pull request merge. Running backport afterwards resulted in this stack trace. Subsequent running kinda got it back in order.

$ ./node_modules/.bin/backport

Thanks for the heads up. Node's exec could be replaced with spawn but bumping maxBuffer should fix it for now.
