Sünkroonimisvigade, or synchronization errors, occur when multiple processes or threads attempting to access or modify shared data at the same time lead to inconsistent or incorrect results. This problem arises in concurrent programming environments where operations are not atomic or are interleaved in an unpredictable manner. For instance, if two threads try to update a counter simultaneously, one thread's increment might be lost if the read-modify-write operations overlap.

These errors can manifest in various ways, including data corruption, deadlocks, and race conditions. Race conditions are a common type of synchronization error where the outcome of a computation depends on the unpredictable timing of events. Deadlocks occur when two or more processes are blocked indefinitely, each waiting for the other to release a resource.

Preventing synchronization errors typically involves employing synchronization primitives such as locks, mutexes, semaphores, and monitors. These mechanisms ensure that only one process or thread can access a critical section of code or shared resource at a time, thereby serializing access and maintaining data integrity. Careful design and testing are crucial to identify and eliminate potential synchronization issues in concurrent systems. Debugging these errors can be challenging due to their non-deterministic nature.
