Hi Tim,
Your command specification is wrong. It will get the -H attribute from
the host_name you should not specify it on the check_command and By
doing so what you have effectively done is write:
check_memcached.pl -H web1.example.com -p web1.example.com 11211
if you enable debug_level=2048 you should be able to see the commands
that Nagios is creating.
