the first call to firebase is very slow > 10 seconds, and some Network error happend. I forked the repo to reproduce the issue: https://github.com/frankpolkm/ionic-conference-app
It simply added firebase to the driftyco/ionic-conference-app demo app. Please have a look at the code change in https://github.com/frankpolkm/ionic-conference-app/blob/master/app/app.ts
and here is the console log. There has no NetWork Error before firebase added.

Please let me know what I did wrong.
Thanks,

Adding <allow-navigation href="*" /> to the confix.xml File solved it for me.

I'm facing some issues on my Cloud Composer instance resulting in failed tasks.
Details of instance configuration :
Composer image : composer-2.0.29-airflow-2.3.3 / Airflow version : 2.3.3
Airflow.cfg :
parallelism = 32 / dag_concurrency = 100 / worker_concurrency = 24
In terms of resources :
I have 60 DAGs which can contains up to 55 tasks that needs to run in parallel.
They don't do any compute, only some light PythonOperator/GCSOperator/BigQueryOperator.
I often encounter this type of errors :
*** Log file is not found: gs://xxx/xxx/attempt=2.log.
*** The task might not have been executed or worker executing it might have finished abnormally (e.g. was evicted).
*** Please, refer to https://cloud.google.com/composer/docs/how-to/using/troubleshooting-dags#common_issues hints to learn what might be possible reasons for a missing log.
All of my tasks have 3 retries but when it happens for a reason it stops at 2 retries and send a failure error. I don't understand why. Example of error in mail sent :
Try 2 out of 3
Exception:
Executor reports task instance finished (failed) although the task says its queued. (Info: None) Was the task killed externally?
I also receives random zombie tasks Detected as zombie
My metrics are the following :
When I clear the task, it succeeds as it should.
(I don't have access to GKE but if it helps I can ask to have access)
Any advice to prevent this errors and understand what happens ?
I have been trying to find help for this problem and there hasn't been too much success. I keep getting this error. I was following this guide: https://cloud.google.com/community/tutorials/cloud-iot-gateways-rpi and I haven't been able to get past step 14.

I was able to successfully get the gateway running but had to manually modify the script. Make sure that you have updated the run-gateway shell script to point to your registry ID and project ID.
If any of the parameters are incorrect (e.g. device, project, region) then your device will be disconnected from the device bridge.
I'm currently using programs based on the Azure-IoT-Hub-C-SDK MQTT examples as well as the samples itself. On my Ubuntu machine, after starting the program, I get a repeating connection error:

press ENTER to end the sample
This happens with both the simplesample_mqtt and the devicetwin_simplesample.
Sometimes the errors don't stop and I have no chance trying the program.
I only changed the connection strings in the samples. The AMQP example (simplesample_amqp) does not show any connection errors and works fine even after starting it several times. On my Yocto board, I also see a few connection errors at every start of a custom MQTT application built on the SDK samples.
Does anyone know a possible cause? I don't know whether it's caused by SDK, IoT hub or my local setup (Ubuntu, Yocto?). I get this error even with a cellular connection and sometimes is also reappears after running fine for a certain time.
Please, if you think I should post more information, request that. Right now I just don't know where to start.
UPDATE:
Right now, nothing is working anymore, I only get errors, the applications don't connect anymore. See the issue on github here:

My app running on an iPhone 4 iOS 8.3 gets this error:

It only happens on the device, it's fine in the simulator (Xcode 7.3).
The phone has 18GB free when the app is run.
This error has shown up in the past, as can be found easily with a search, but on writes; this app only reads the database, never writes.
There's no problem on iOS 9 devices.
What's the next thing to check?
The Realm file is mmaped whether it is opened as read-only or read-write. Unfortunately, this is probably an issue inherent to the resource constraints of the iPhone 4/4S. We've seen issues with mmap ranging from files as small as 300 MB, depending on the device.
You can check out this Github issue for some potential workarounds.

It seems is an error from the uuid module, try to downgrade the version to 7.x-1.0-alpha5 and I think it fixes the error.
You can download this version here.
