No, I don't use DJango.
It does seem to be more likely on a cold instance, but probably
because there is more actions that can potentially fail in such a

The logs simply show everything is just taking way too long. It's like

Also, a cold start for this task can take as little as 960 ms (where it
shows the log detail: "This request caused a new process to be started for

of the running time.

My app is extremely lightweight.
The average CPU usage for a cold start falls in these ranges:
CPU_MS:1030 - 1230

2. Connect to gdata service, and get some data.

When I refer to bursts of errors, this is an example of what I mean.
This is a query for any 500-series errors against appid: steprep. Note
how close together the log entries are (i.e., the bursty-ness). These
requests operate very quickly when App Engine is performing well.

Jason, are you calling URLFetch/datastore/Memcache in that action?

Yes, in the /_ah/queue/deferred requests, we are almost certainly
doing datastore/memcache work and very likely doing urlfetch work (I'm
referring to this probabilistically, because we use deferred for many
things).
BTW, appid steprep is Python.
