I'm noticing excessive datastore delays today (M/S), and generally a lot of API calls timing out. Might be related. Errors like:
*DeadlineExceededError: The API call logservice.Flush() took too long to respond and was cancelled.* Also: *<class 'google.appengine.runtime.apiproxy_errors.DeadlineExceededError'>: The API call urlfetch.Fetch() took too long to respond and was cancelled.* On Tue, May 22, 2012 at 12:04 PM, Gayle Laakmann <[email protected]> wrote: > I think I'm having the same issue. > > How did you get that look at memcache latency specifically? > > On May 22, 9:41 am, Rishi Arora <[email protected]> wrote: > > Ah, I was mistaken.
