[google-appengine] Deadline exceeded error when deploying GAE flex app
I've been using GAE flex for about six months, and starting yesterday, I get this error when deploying with gcloud app deploy: > ERROR: (gcloud.app.deploy) Error Response: [4] Flex operation > projects/MY-PROJECT/regions/us-central1/operations/xxx > error [DEADLINE_EXCEEDED]: An internal error occurred while processing > task > /appengine-flex-v1/insert_flex_deployment/flex_create_resources>2019-09-04T21:29:03.412Z8424.ow.0: > Gave up polling Deployment Manager operation > MY-PROJECT/operation-xxx. I don't see any helpful info in my logs. The app runs fine locally and I haven't done any major code changes since the a successful deploy a few days ago. I wonder if I have somehow inadvertently changed a setting. I did turn on Cloud Web Security Scanner, but I wouldn't expect that to cause the problem. I set cloud_build_timeout to 600 (what I think is the default anyway) but that didn't help. Any ideas how to fix this? Should I set custom values for initial_delay_sec or app_start_timeout_sec? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Deadline Exceeded Error even with a TaskQueue running on a Backend
I'm having some issues with *Deadline Exceeded error*. Basically I'm doing some webscrapping in an URL using *Mechanize*. So when trying to perform br.open(url) I have this error HTTPException: Deadline exceeded while waiting for HTTP response from URL: my-url I have read the documentationhttps://developers.google.com/appengine/articles/deadlineexceedederrors where it says to use *Backends* (I'm using a dynamic backend, B4_1G class with 5 instances), but still having this error happening in 60 seconds. And according to the docs, when using *TaskQueue* and *Backends* the timeout should be extended to 10 minutes. Here is how I assign the operation to be runnnig on a TaskQueue with it's target on the first instance of my Backend. taskqueue.add(url='/crons/myworker', target='1.myworker') Here is the backends.yaml. backends: - name: myworker class: B4_1G instances: 5 options: dynamic Any ideas of what might be happening?

[google-appengine] deadline errors for pages which normally load fast
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.

[google-appengine] Deadline Exceeded Exception on loading requests leaves bad instance running
We've seen some Deadline Exceeded Exceptions cropping up on loading requests again. This used to be commonplace (a couple of years ago), but I haven't seen it for a long time... until recently. Has anyone else seen this lately? We're seeing it on Py2.7. Normally, these apps warmup in a couple of seconds, so 60-70s startup times are completely abnormal. Worse, when this occurs during a loading request, the instance is left in a partially inflated state - in our case, basically all subsequent requests fail with import/pythonpath issues. Our recourse, once we discover this is happening, is to manually kill the instance. This really, really sucks. Can anyone make an argument why you would *want* to keep an instance that Deadline Exceeded Exceptions on a loading request? I can't. I think an instance that hits a Deadline Exceeded Exception during a loading request should be thrown away as suspect. j -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Deadline exceeded errors, huge latency, very high number of instances, entities not deleting
Over the past several weeks (months?) we've noticed an increased amount of DeadlineExceeded / Timeout Exceptions on our app, which involve a very large delay (71476ms, 72460ms, 61287ms, 91551ms, etc) and often occur on the smallest of queries... even requests that do not do any database queries, such as static files. The appengine status page shows there's never been a problem. Here's an example of a crash that took 86168ms to fail, which was (as far as I can tell) loading a css file: 2012-01-17 13:29:21.745 /stylesheets/all.css 500 86168ms 0kb Mozilla/5.0 (iPhone; CPU iPhone OS 5_0_1 like Mac OS X) AppleWebKit/ 534.46 (KHTML, like Gecko) Mobile/9A405 66.87.122.80 - - [17/Jan/2012:13:29:21 -0800] GET /stylesheets/ all.css HTTP/1.1 500 0 http://www.[redacted].com/; Mozilla/5.0 (iPhone; CPU iPhone OS 5_0_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/9A405 www.[redacted].com ms=86168 cpu_ms=93 api_cpu_ms=0 cpm_usd=0.002640 loading_request=1 pending_ms=9836 exit_code=104 instance=00c61b117c5cab753f44bfade2e47d4169dc E 2012-01-17 13:29:21.737 class 'google.appengine.runtime.DeadlineExceededError': Traceback (most recent call last): File /base/data/home/apps/[redacted]/3-0-0.356168683702691497/ extension/extension.py, line 14, in module from extension.entry_application import EntryApplication File /base/data/home/apps/[redacted]/3-0-0.356168683702691497/ extension/entry_application.py, line 9, in module from application_controller import ApplicationController File /base/data/home/apps/[redacted]/3-0-0.356168683702691497/ extension/application_controller.py, line 11, in module from django.template import Context File /base/python_runtime/python_lib/versions/third_party/ django-1.2/django/template/__init__.py, line 50, in module I 2012-01-17 13:29:21.738 This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time.

This is likely to cause a new process to be used for the next request to your application. If you see this message frequently, you may be throwing exceptions during the initialization of your application. (Error code 104) - We are also experiencing what I would consider is not proper instance ages... we rarely see any of our instances live for any longer than 10 minutes, as we hit these deadline errors constantly (we're serving thousands of queries per second, so one of these errors are bound to hit an instance eventually, thus killing it and needing a new one to start up in its place). We used to be running (and paying for!) almost 1,000 instances at any one time, even though if we turn it off Automatic, we only use around 200. Another new problem that has started showing up in the last few days has been content that suddenly duplicates many times over, and then cannot be deleted... we execute an entity.delete(), but the entity is still viewable. If I edit the entity by hand in the Datastore Viewer, then run the same entity.delete(), it says the entity is gone in the Datastore Viewer, but then only a few seconds/minutes later it has returned. I am extremely concerned by these timeout/instance problems for a few reasons: 1) we're paying a lot for this service 2) the processes that are timing out and killing instances are many many times more expensive than properly-executing queries that we are running on our site. I'm willing to pay for a query I made that takes 2000ms to execute, but not an instance loading process that I don't have control of that dies after taking 9ms. 3) I'm seeing a lot of discussion threads documenting issues which are very similar to our problem, and haven't seen any Google response aside from replies of switch over to the HRD, because it's more stable. Unless you have stated that you are deprecating the master/ slave system, that's not an answer to the stated problems with the existing (and previously working and stable) system. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] DEADLINE Exceeded Messages ?!
I continue to be plagued by deadline exceeded messages, even when requesting a jpg file from within a zip file. I find it hard to believe that the individual request is responsible for the deadline exceeded. What circumstances could cause this error? # 1. 12-18 03:35PM 36.823 /Photos/P200512048/2277/Benchmark315br.jpg/ 500 8769ms 23782ms-cpu 1kb See details 76.14.31.214 - derrickrburns [18/Dec/2008:15:35:45 -0800] GET / Photos/P200512048/2277/Benchmark315br.jpg/ HTTP/1.1 500 1323 http:// vhac.appspot.com/search?location=angel+fire%2C +nmbedrooms=bathrooms= - 2.

[google-appengine] DEADLINE Exceeded Messages ?!
I am consistently getting Deadline exceeded messages. The problem is that my individual requests are trivial: do a query or two to BigTable, serialize the results, and return them. So, what could be causing these messages. How are deadlines actually measured on app engine? In my case, I am sending a number (10-50) of requests in parallel. Each individual request retrieves a single row in a table plus one or two rows in related tables. I would guess that that CPU time usage is measured by interrupting the thread serving a request at regular intervals. The question is, how does this interrupt ascertain whether a CPU deadline has been exceeded. I hypothesize that when the poller wakes up, it checks to see which application has the cpu, and adds a tick to the count for that user. If the same application is using the CPU as the previous time the poller awoke, then the poller checks to see if the tick count exceeds the deadline. If so, it initiates a deadline exceeded message and terminates the request. If this is the algorithm, then it is very problematic for me. Will someone from the Google App Engine team explain to us the workings of the Deadline measuring algorithm so that we can adjust our application for work on the platform. Also, could the problem have anything to do with indexing? Our queries are dirt simple: a single query parameter, so we do not generate indices for them manually. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] deadline exceeded errors
This morning my application has been receiving deadline exceeded errors for many requests, including some that usually take very little time to process. My code has not been updated recently, so I suspect this is an environmental issue. Also, the app engine dashboard is currently down (Application statistics are currently unavailable.). Anybody experiencing similar problems? -Joey --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.
