What is zombie state in Unix?

A zombie process is a process that completed execution but still in process table. When a process ends, all of the memory and resources associated with it are deallocated so they can be used by other processes. However, the process's entry in the process table remains. The parent can read the child's exit status by executing the wait system call, at which stage the zombie is removed After the zombie is removed, its process ID and entry in the process table can then be reused. However, if a parent fails to call wait, the zombie will be left in the process table. In some situations this may be desirable, for example if the parent creates another child process it ensures that it will not be allocated the same process ID.

Could a zombie outbreak happen?

i personally belive yes check out my page GLitch378 No, despite the zombie apocalypse depicted by hollywood. Being a zombie is not a contagious condition - you do not become a zombie by being killed by a zombie or by simply being dead. It requires a voodoo priest to make each and every zombie and the process is not trivial.
