The Problem
The server continuously displaying below messages in /var/log/messages or dmesg log file:
avahi-daemon[23373]: server.c: Packet too short or invalid while reading response record. (Maybe an UTF8 problem?)
The Solution
This is avahi-daemon issue related to network environment. The avahi-daemon is application for zeroconf implementation. The avahi-daemon working related of to DNS(mDSN). The avahi-daemon approaching and searching to each other user or devices for local network without special configuration as DNS or servers. This message displays that received any packets from other host devices or DNS. It means are avahi-daemon received unsuccessful response on the network.
If you are not using Zeroconf/avahi-daemon, please disable to avahi-daemon:
# service avahi-daemon stop # ckconfig avahi-daemon off
Also, if you can see NetworkManager processes, please diable to NM, too :
# service NetworkManager stop # chkconfig NetworkManager off
You can also remove the avahi-daemon packages from the system completely. But the avahi-daemon libraries may have been used in many other packages and thus will have dependencies. Also the package may get installed again as a dependency while installing other packages.
