134217728 bytes is precisely equivalent to 128 Megabytes (MB).
This value typically signifies a memory allocation limit for software applications or scripts. It defines the maximum Random Access Memory (RAM) a process is allowed to consume during its execution.
Common Scenarios & Implications
- PHP Memory Limit: This specific byte count is frequently encountered as the default or configured
memory_limit
in PHP environments (often expressed as128M
). If a PHP script attempts to allocate more memory than this limit, it will trigger a fatal error, commonly displayed as: "Fatal error: Allowed memory size of 134217728 bytes exhausted". - Application Configuration: Various other software applications or server processes might use this value (or its MB equivalent) as a predefined memory cap to ensure system stability and prevent resource monopolization.
- Error Indication: Encountering this number in error messages almost invariably points to a process attempting to use more memory than it has been permitted.
When this memory ceiling is reached, the operating system or the application runtime environment typically terminates the offending process. Addressing such issues involves either increasing the allocated memory limit (if feasible and justified) or optimizing the application code to reduce its memory footprint.
