Hi everybody and thank you for your help. I finally managed to workaround my issues. I implemented a similar solution to the one described in the Objectify documentation : https://code.google.com/p/objectify-appengine/wiki/Queries#Cursor_Example. It's also really close to the solution suggested by husayt, except that it enqueues a new task to prevent the 10 minutes timeout. I have to compute only 300 entities in a task, and then, enqueue a new task (saving the state in query parameters or in the blobstore).
This works, but I still can't explain why it fails after ~3 minutes. I'd really like to be able to increase the amount of entities computed in one pass. Disabling global cache (ofy().cache(false)) and clearing the session cache (ofy().clear()) didn't help. Moreover, I couldn't notice any peak in my dashbord which could have explained the failure. Still a mistery for me :( . Thank you. G.
