### Description

    HADB-E-05521: Operation on semaphore with key "46025" failed, OS status=28 :
    No space left on device

This can be caused when the number of semaphores is too low. Since the semaphores are provided as a global resource by the operating system, the configuration depends on all processes running on the host, not only the HADB. This can occur either while starting the HADB, or during runtime.
