What are the consequences if a goroutine's execution is stopped due to a lock?

If a goroutine in Go is stopped due to blocking (for example, waiting on a mutex, channel, or system call), the goroutine itself is suspended, but the Go scheduler (runtime scheduler) continues to run and switches to executing other goroutines.

However, if the blocking occurs at the system call level that does not release the thread, or if all goroutines are blocked and there are no active ones to run, the program may "hang" or stop progressing.

It is important to design code to avoid long blocking periods and to use non-blocking constructs or timeouts. Overall, blocking one goroutine does not stop the entire process, thanks to Go's concurrent model.
