I have some linux servers with alerts of processes with STATE = RSZDT by monitor Nagios.

That is not 1 state, but rather a combination of process state codes.  If nagios is alerting for that while the server is under normal load, then you need to increase the alert threshold.

D       Uninterruptible sleep (usually IO)
R       Running or runnable (on run queue)
S       Interruptible sleep (waiting for an event to complete)
T       Stopped, either by a job control signal or because it is being traced.
W       paging (not valid since kernel 2.6.xx)
X       dead (should never be seen)
Z       Defunct ("zombie") process, terminated but not reaped by its parent.

OK, but there is "sh" or "script" to kill processes with state "Z" and "D".

Are you sure you have processes in those states?  It's not abnormal to see a few Z's now and then, but usually they get cleaned up.

If you have Z processes, either kill the parent if possible or just deal with it, they consume no resources.
If you have D processes, same thing applies about the parent, however if you have a ton of these you definitely have an I/O problem.

Basically you shouldn't have to automate killing those processes, you should fix the source of the problem.

However if you really want to, you can give this a shot.
