A user reports that their application occasionally freezes. You suspect it's due to the application waiting for some I/O operations to complete. Which state might the process be in during these freezes?

  • D (Uninterruptible Sleep)
  • R (Running)
  • S (Sleeping)
  • Z (Zombie)
During an I/O operation, a process might enter the "D" state, which stands for Uninterruptible Sleep. This state indicates that the process is waiting for a resource to become available, and it cannot be interrupted. It's often associated with I/O-related delays or problems.
