This is an issue within Google AppEngine. For some unknown reason, it
occasionally gets 'stuck' while trying to activate the application
(presumably reading the application files off of its disk drives and
unzipping them). This always happens in the 'unzipping' stage, as indicated
by the error trace in the log (excerpt below)). After expending 60 seconds
trying to unzip its files, AppEngine kills ODK Aggregate (all requests to
AppEngine must take 60 seconds or less to run).
Under normal conditions, ODK Aggregate takes 27 seconds to start up, so
this means Google AppEngine was experiencing a 2x slow-down.
I know of no work-around for this problem.

Added several users for a demo and today found my instance of Aggregate
inaccessible today w/ a long list of errors in the logs, the first being
"Context initialization failed." I've attached a copy of the log from one
attempt for reference. I will create a new instance to replace this, but
would appreciate any guidance on what I might do to fix or avoid this
problem in the future.Thanks,
Chris
