[Developers] Simple cursor query times out

[Jonathan del Strother]

Hi,
I'm trying to page through a list of films, with the following query :
[{"initial_release_date": null, "type": "/film/film",
"initial_release_date>=": "2008-10", "name": null}]

- ie, get a list of films released since October, with their names &
release date.
Which works fine for 4 requests, then fails when I try and fetch with
the cursor "eNpVj91qwzAMhR9mDGJKiCRbsizG6HuEXHhJVgpdUtxsz7-Qph3T5fn5Duq_y20uljmptbMFgK6dDCMkCeR9l6fBXqBeBQ6sEY2sOt-ybdKWIbu81dVPydNpXIscFUN8ut7mfhkXIwB9pQGhNqtOX_l6j0aWB1vFlvp9B0gDjTPn_rb2-W3rvLcF9GmRlUMioKw9rF-ABPxU-Hf9jgeJzrXXMht0DYpw8sTaHDl9MOKowxiQsw-IEX8BA8xGTQ=="

Any suggestions why?

Thanks,
