How to Increase AWS Lambda Memory Beyond 3008 MB Cap

Select Language:

If you’re having trouble with Lambda function memory limits and seeing a restriction of only 3008 MB, this is likely due to a temporary limit applied to new AWS accounts. This restriction isn’t part of the usual memory limit for Lambda functions; it’s just a new account safeguard that AWS puts in place initially.

Typically, AWS accounts can allocate up to 10,240 MB, or 10 GB, of memory to Lambda functions, with the ability to choose increments of 1 MB. If your account still has the memory cap at 3008 MB, it means the account-level restrictions haven’t been lifted yet.

You can’t simply request an increase in this quota through the standard Service Quotas tool. Instead, you’ll need to contact AWS Support to have the limits reviewed and removed. This process involves a few steps:

– First, open a support case with AWS Support. Be sure to select a support plan if you haven’t already. When creating the case, specify that you need the memory limit restrictions for Lambda in the us-east-2 region removed from your account.
– Provide details about your use case, particularly your work with the machine learning model inference, so support understands why you need more memory.
– Request that the default Lambda memory limit of 10,240 MB be applied to your account.

If you don’t have a support plan, you might need to wait until AWS automatically lifts the restrictions as your account ages, or consider upgrading to at least a Developer Support plan so you can open support tickets.

Since the memory you need—4,096 MB—is well within Lambda’s standard limits, the main task is to get the account restrictions removed. Once done, you’ll be able to set your function’s memory to suit your U2-Net model inference tasks, ensuring smooth operation.
