Not enough memory available with recent update

After updating my CLI and rack today I am unable to deploy an update to an app successfully due to ‘ERROR not enough memory available to start process’ on build. I have tried changing the cluster to 3 x 8GB (up from 4GB) instances and also decreasing the BuildMemory and eliminating the build instance altogether. Both the CPU and Memory reservation % is also now much higher than it should be, not sure if this impacts the deploy. The app has not changed in size. Any ideas on what is causing the issue?


Did you figure out why?
