Since I upgraded our servers to ZCM 11 SP4 xinetd failed to start, even manually with /etc/init.d/xinetd start.

Here is the /etc/xinetd.conf content:

I don't know if it is related but sometimes server hangs on this while shutting down:

And also while booting:

Strange thing is that I upgraded two primary servers since yesterday and the problem is exactly the same on both of them.

How can I solve this issues?

Thanks in advance.
