When using the command line to install packages through npm or ea-podman, you receive the following error, and installation fails:
pthread_create: Resource temporarily unavailable
By default, WHM enabled Shell Fork Bomb protection to prevent shell processes from opening too many processes, which can consume server resources. This can sometimes prevent installations from opening the child processes required as part of the installation.
Access "WHM / Shell Fork Bomb Protection" and disable it, then re-run the installation. You can then re-enable the protection when the installation is complete.
