The server has 8 GB of memory, and we run an application that consumes 10 GB. What will happen?

If a server with 8 GB of memory runs an application that tries to consume 10 GB, the system will encounter a shortage of RAM. Depending on the operating system and settings:

• The application may encounter a memory allocation error (e.g., out of memory), leading to a crash or forced termination.
• If swap is enabled, the system will start using disk space as an extension of memory, which will significantly slow down performance.
• In Linux, the OOM-killer may activate — a process that terminates applications to free up memory.

In Go, if an application tries to allocate more memory than is available, it will encounter runtime errors, and the program may crash with a panic.

It is important to monitor memory consumption and optimize the application according to available resources.
