I am seeing deadline failures such as the one below -- 61 secs. Using python 2.7, appid ogeekcom. Notice it doesn't say deadline error -- it appears that somebody is broken in the GAE logging code but based on the 61 seconds I have come to believe it is a deadline failure.
Just loaded the same page in 208 ms. Many times they are associated with a memcache set failure, but sometimes other failures, e.g. blob url_serving error. I use the 1 gig premium memcache even though I don't need nearly that much cache and hate the cost at $90 a month. I saw almost 40 of these errors overnight ... clustered around a couple of times. When that happens, instances are created for each URL because the request takes so long to finish .... ouch. 1. 2013-11-04 14:04:27.457 /viking-international-llc 500 61941ms 0kb Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) 66.249.66.180 - - [04/Nov/2013:14:04:27 -0800] "GET /viking-international-llc HTTP/1.1" 500 0 - "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" "www.goobafoo.com" ms=61941 cpu_ms=3850 app_engine_release=1.8.6 instance=00c61b117c74a9c539d5b4ef839de2da2a3a8a3f <https://appengine.google.com/instances?app_id=s~ogeekcom&version_id=1383584138-1576.371403051099549606&key=00c61b117c74a9c539d5b4ef839de2da2a3a8a3f#00c61b117c74a9c539d5b4ef839de2da2a3a8a3f> 2.
