What is Error 105?
The ERROR_SEM_OWNER_DIED error, represented by the code 105, signifies that a semaphore, which is a variable used to control access to a common resource by multiple threads, has lost its owner. This can happen due to various reasons such as a thread terminating unexpectedly or a process crashing, leading to the semaphore being left in an unstable state. When this error occurs, it can lead to system freezes, crashes, or unpredictable behavior, especially in applications that rely heavily on multi-threading for their functionality. Understanding the role of semaphores in synchronizing access to shared resources is key to diagnosing and fixing this error. In Windows systems, semaphores are used to prevent race conditions and ensure that only a specified number of threads can access a resource simultaneously. The termination of the owning process or thread can leave the semaphore in a state where it cannot be properly released, hence triggering the ERROR_SEM_OWNER_DIED error.
Common Causes
- Abrupt termination of a process or thread that owned a semaphore
- Inadequate error handling in multi-threaded applications
- System crashes or blue screen of death (BSOD) due to driver issues
