Disable AVIF. start the container using docker run. When plenty of CPU cycles are available, all containers use as much CPU as they need. Well, we're not able to build an application on a server which is perfectly able to run the app once its built. This makes it more There seems to be a strict ceiling for memory usage in node (around 1-2 GB on most 64-bit systems). Container built with normal user ( USER XXXXX used in docker file) to run the application. However, this exercise demonstrated that the JVM needed significantly more memory (20%) that what is implied by its heap settings, even for nearly the simplest possible Java webapp. FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory This generally occurs on larger projects where the default amount of memory allocated by node (1.5gb) is insufficient to complete the command successfully.

Once I faced this issue in one of my application, first I tried to build the application using below command instead of ng build. I can assure you that you can easily do better than the defaults, especially when it comes to memory limits and high throughput workloads. Verify that CONFIG_RT_GROUP_SCHED is enabled in the Linux kernel by running If the kernel or Docker daemon is not configured correctly, an error occurs. For larger projects, we can add a ceiling of as much as 12-14 GB, considering the project is large enough. Why are trials on "Law & Order" in the New York Supreme Court?
