The development team at an IT company has set up an Application Load Balancer (ALB) to route requests to a Lambda function named A. However, they have noticed that Lambda function A is not processing any of the requests sent by the ALB. Upon investigating the issue, they discovered that another Lambda function, named B, operating within the same AWS account is surpassing the concurrency limits set for their Lambda functions.

What steps can the development team take to resolve this problem?
