Hi all,

Whilst investigating the Java Buildpack out-of-memory issues David Head-Rapson mailed about the other day, we discovered a discrepancy between the memory usage stat provided by `cf app` and the value stored in the corresponding cgroup's `memory.usage_in_bytes` file. The latter seems to be bumping right along the maximum allowed.

Does anyone know why the latter is so high, and why it would differ from what the DEA reports back to the Cloud Controller? There's clearly a gap in our understanding somewhere, so any help would be much appreciated.

Many thanks,
