Thanks for replying.

I really would love to use TCP. But I'm dealing with several legacy 
network/telecomm devices, and most of them doesn't support syslog under TCP.

I really need to deal with UDP.

Just applied reusable sockets to the configuration.

More configurationĀ  I tried that gave me better results: mem-bug-length 
and disk-buf-size : The data loss reached zero.

Got one more doubt: While reading a pipe with cat command, is it normal 
to get cat closed while there are messages streams being processed?
