Monit was not able to detect that the process is running - maybe the user under
which Monit is running has no access to the "/var/run/memcached.pid" file? (you
can check it with "ls -l ...")
Did the process really started? Monti sets spartan environment for the start
program execution - maybe your start script depends on some environment
variable or some extended PATH or LD_LIBRARY_PATH?
Alternatively you can use pidfile-less monitoring:
check process memcached matching "memcached"
...
