Have you encountered an OOM (Out Of Memory) error?

OOM (Out Of Memory) error occurs when an application or system tries to use more RAM than is available. This can lead to crashes, hangs, or forced termination of processes.

Causes of OOM:

• Memory leaks — objects are not released and accumulate.
• Processing too large volumes of data in memory.
• Recursive calls without an exit.
• Improper resource management.

How to deal with it:

• Use memory profiling to identify leaks.
• Optimize algorithms to avoid holding large data in memory.
• Use streaming and lazy evaluation.
• Limit recursion depth.
• In managed memory environments (e.g., JavaScript), monitor object references.

Example: if a Node.js application reads a very large file entirely into memory, it is better to use streaming to process data in parts and avoid memory overload.
