What is the maximum memory a Google App Engine app may consume?

Question

What is the maximum amount of local memory (not Memcache) each instance of a Google App engine app is allowed to consume?

I couldn\'t find any inform

Answer 1

The maximum amount of local memory is not documented.

speculation:
I believe they have not imposed any hard limits because it may depend on your application traffic/load/activity and by other GAE applications.

There's an open issue MemoryError undocumented/hard to predict that you might want to star.

EDIT:
Reading the new Backends documentation here it seems capped to 128MB
