consider 3 processes, proc1 proc2 proc3 accessing a shared memory based ring buffer. Let these 3 processes attach that memory segment. My question is, what happens when proc1 is chrashed or died? In that case, what happens to the shared segment attached by it? will it affect other processes?

if dealing with shmem, the data survives a dying process.
