What limitations can arise when working with shared memory segments?

Answer from AI

When working with shared memory segments, the following limitations may arise:

  • Synchronization of access: Multiple processes can read and write to the segment simultaneously, requiring synchronization mechanisms (mutexes, semaphores) to prevent data races.
  • Limited size: The size of the segment is limited by system parameters and may be insufficient for large data.
  • Lifecycle management: Segments must be created and deleted correctly; otherwise, "dangling" segments may remain, occupying memory.
  • Access rights: Proper access rights must be configured to prevent unauthorized access.
  • Compatibility: Different architectures or software versions may interpret data in memory differently.

These limitations require careful design and control when using shared memory.
