Êàæåòñÿ, íàøëîñü îáúÿñíåíèå:

Defunct (or zombie) process is a process that has terminated (either because it has been killed by a signal or because it has called exit()) and whose parent process has not yet received notification of its termination by executing (some form of) the wait() system call.

A zombie process exists solely as a process table entry and consumes no other resources. This entry is retained to hold the child's exit status until the parent process wants to retrieve it. The parent can also be notified asynchronously via a signal of the child's termination.

So this process doesn't consume any resources other than one entry in the process table. As jools already pointed out, there is no reason to worry about this process unless you have many defunct processes. If you have many defunct processes process table can get filled and you won't be able to start new processes.
