Could not create sample bucket after reducing bucket memory

Saw this once, but couldn't reproduce. Here's what happened:

1. Provision a new system with no sample buckets and with the default bucket taking all the memory
2. Reduce the default bucket memory to allow a sample bucket to be created
3. Navigate to Sample Buckets tab under settings and click on a sample bucket
4. Get the "Your cluster does not have enough RAM to create a sample bucket" error message

I navigated to another tab and when I came back to the sample buckets page everything was fine.
