I'm getting an error pushing any app during the staging step. The cf logs
returns only this:

Obviously something is misconfigured, but I'm not sure what. I don't know
why the out of memory thing is appearing as the memory being used by the
test app i've pushed is tiny (64M app with staticfile buildpack) and the
dea config has resource.memory_mb set to 8 gigs and staging.memory_limit_mb
set to 1 gigs. Is there some config I'm lacking that's causing this to fail?
