QUESTION
I'm using the SeleniumGrid in the most recent version 4.1.2 in a Kubernetes cluster.
In many cases (I would say in about half) when I execute a test through the grid, the node fails to kill the processes and does not go back to being idle. The container then keeps using one full CPU all the time until I kill it manually.
The log in the container is the following:
...ANSWER
Answered 2022-Mar-07 at 13:27If you don't need to use Xvfb you can remove it from your code and your problem will be resolved.
Apparently the issue resolves when removing the
START_XVFBparameter. With a node with only the timezone config I did not yet have the problem.
For the workaround you can try to change your driver for example to Chromedriver. You can read about the differences between them here.

I have a Cloudformation template to create an event bridge rule with target to a central event bus running in another account. When i run the below code , both IAM role and event bridge is getting created but the IAM role is not getting attached to eventbridge rule. Below is the yaml template i am using.
Please see the attached screenshot also.
...ANSWER
Answered 2022-Feb-07 at 06:36Cross-account permissions are not set using role, but EventBus resource permissions. From [docs][1]:
The permissions for an event bus are granted or denied using a resource-based policy attached to the event bus.
To do this in CloudFormation, you have to develop your own custom resource.
Update
You haven't specified RoleArn for your target. This is different RoleArn that you have now.
QUESTION
I'm using AWS Eventbridge and I have the exact same rule on my default bus as on a custom bus. The target for both is an SQS queue. When I push an event I can see a message on my queue which is the target of the rule of my default bus.
I don't see anything on the queue of the rule of my custom bus. Also the metrics don't show an invocation. What am I doint wrong? I've created a custom bus.
I tried both without any policy as with the following policy:

Answered 2022-Jan-24 at 11:31Your custom bus will not receive any "aws.ssm" events. All aws.* are going to default bus only. The custom bus can only receive custom events from your application, e.g.:

My app is running fine on version 1.10.24 and 1.10.25.
Recently I am trying to update packages and moved to 1.11.3 and I am starting to get error.

QUESTION
I'm trying to manage Lambda retries in a situation where Eventbridge asynchronously invokes a Lambda function via an events rule (see template at bottom)
I've tried to configure retry behavour on both Eventbridge and Lambda sides, in particular -
Event rule max retry attempts set to zero, and dead letter queue configured
Lambda event config configured with max retry attempts also set to zero, and Lambda destination queue also configured
I can push a "good" message to Eventbridge -
...ANSWER
Answered 2021-Nov-19 at 10:14Try setting Qualifier: $LATEST on MyFunctionEventConfig.
As you say, the observed behaviour is consistent with the MyFunctionEventConfig Destination not being called at all. I suspect that is because you have qualified the Destination with a newly created Lambda version MyFunctionVersion. But I do not believe you are ever invoking that version. So the Destination also never gets invoked.
Unless your AWS::Lambda::Version is doing work for you, you can delete it and use Qualifier: $LATEST.
Edit - Further info:
Triggers and destinations are version dependent, as each lambda version has its own ARN.
You can test this in the lambda console without redeploying. If the version-hypothesis is correct, the destination will not appear in the "Function overview" section of the lambda console, UNLESS you first select the snapshotted version.
