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?
