Explanation
Guardian error 12 represents 'File is in Use' - meaning the requested file is locked by another process. This is a file access conflict error, not a file-not-found or file-full error. The file exists but cannot be accessed due to an existing lock.
AI explanation
In HP NonStop (Guardian) systems, error 12 is the standard file-system error code indicating the file is currently in use by another process and cannot be accessed as requested. Distinct codes are reserved for other conditions such as a full file (no space to write), an invalid file, or a file that can't be located, so error 12 specifically maps to the "in use" condition.
