Description of problem:
minor error in /etc/xinetd.d/bitlbee
of bitlbee-3.2.1-3.el6.x86_64 (as of today that is in epel-testing)

the file has the line
server          = /usr/sbin/bitlbee -I

the -I needs to go into server_args or can be dropped altogether as -I is default.

this works for me on my server;

# cat /etc/xinetd.d/bitlbee 
## xinetd file for BitlBee. Please check this file before using it, the
## user, port and/or binary location might be wrong.
## This file assumes you have ircd somewhere in your /etc/services, if things
## don't work, check that file first.
service ircdocol        = tcp
{       wait            = no
        disablem= nolikely want to change these two
        socket_type     = streame
        protocol        = tcpr/sbin/bitlbee
        wait            = no limit access to localhost only:
        ## You most likely want to change these two
        user            = bitlbeean for telling us about the type
        server          = /usr/sbin/bitlbeee used without having to edit
        ## You might want to limit access to localhost only:
        bind            = 127.0.0.1
        ## Thanks a lot to friedman for telling us about the type
        ## argument, so now this file can be used without having to edit
}       ## /etc/services too.


Without this change one gets the expected
attribute server expects 1 values and 2 values were specified [file=/etc/xinetd.d/bitlbee] [line=13]
