AWS Marketplace CouchBase /boot Partition too small?

Hi There:

In a fresh instalation from AWS Marketplace (CouchBase version 3.0) the /boot partition has 83% used, as it grows
the number of documents, the partition reaches more than 90% of its
usability and an alert is sent.

I’ve noticed that even changing the path for storing the data to a larger partition, the problem persists.
What can be causing this? as can be avoided?

Thanks in advance,

Jorge
