Since yesterday I'm getting this error as well. But according to
AppEngine status (http://code.google.com/status/appengine) everything
is working fine.

Any idea ? Thanks

My application is: http://www.cocoslive.net

Check your logs. I wonder if you will find in them something like "Too many open files".

I didn't find any log with the word "many".
What's strange is that I didn't push any modification. The server is
still throwing that error, and I don't know how to fix it.
Any ideas ? Thanks.

Can you see any exceptions thrown in the logs?

Yes, many exceptions. This exception is new one for me:

cocoslive is a High Score server, and now almost all the games are
throwing the "Deadline" exception.
this is another example:

I would like to mention that I didn't modify anything on the server.
From 1 day to another the server started to throw this error :-(

[Ricardo Quesada]

Did the transaction code change ? Did the DEFAULT_TRANSACTION_RETRIES
change in the last update ?

[gg]

I'm getting tons of Deadline Exceeded Errors also.... Somebody screwed
something up.....

[Ricardo Quesada]

Can anybody can help us ?
I'm paying more than $80 per week for this service!!!!!

Did the API change ? Do we need to update something ?

It looks like you're hitting the 30 second timeout limit during a
fetch from the datastore. How many entities are you fetching in this
query? Does the number fetched constantly increase the more usage
your app gets?
