In one of my box, I see special characters being added to "/etc/hosts" file. Not sure what is causing this. Any idea on how to debug this ?

You can try to use the lsof command to see what process opens the file.
For example:
$ sudo lsof /bin/ping
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ping 4216 amit txt REG 8,1 64424 1048708 /bin/ping
It will be trickier to catch it if the process doesn't keep the fd of the file open though...
