Glue job does not delete interfaces that are not in use

Question

Hello,

I have a glue job that connects to databases using a vpc. Each time the job is executed, a new VPC interface is opened, but it is not finalized at the end of the execution.
Today I had an elastic network limit problem. "*Elastic network interface limit is exceeded. Please increase your elastic network interface limit*"

Is there any way to configure to always delete the interface when the job finishes executing?

Answer

ENIs used by Glue jobs are deleted after a certain time when they are no longer used.  
We believe that the following documents should be reviewed and countermeasures taken.
