How are you giving anything different arguments?  I only see one service
configured in your rc.conf.

So, you have memcached1.sh :

#!/bin/sh
#

# PROVIDE: memcached1
# REQUIRE: NETWORKING

#
# Add the following lines to /etc/rc.conf to run memcached:
#
# memcached1_enable="YES"
# memcached1_flags=""
#
. /etc/rc.subr

name="memcached1"
rcvar=`set_rcvar`
command=/usr/local/bin/memcached
command_args="-du nobody ${memcached1_flags}"
load_rc_config $name
run_rc_command "$1"

And then you have memcached2.sh :

#!/bin/sh
#

# PROVIDE: memcached2
# REQUIRE: NETWORKING

#
# Add the following lines to /etc/rc.conf to run memcached:
#
# memcached2_enable="YES"
# memcached2_flags=""
#
. /etc/rc.subr

name="memcached2"
rcvar=`set_rcvar`
command=/usr/local/bin/memcached
command_args="-du nobody ${memcached2_flags}"
load_rc_config $name
run_rc_command "$1"

And you set memcached1_flags and memcached2_flags in rc.conf where you
were setting memcache_flags formerly.

However, unless you really know what you are doing, if you are trying to
run TWO memchached instances, I'd suspect, as another has asserted, that
your understanding of memcached is flawed.  I'd check with the memcached
community to see if there isn't a better way to get things done in the
first place.
