Hi Pramod,

First of all the version of memcached you're using is old. Upgrade. The
latest version is 1.4.5 with another release being imminent from what I
hear. Available from here: http://memcached.org/

You can take a look at this Perl script. It's a handy way to dump the
contents of your memcached instance for further examination. Just don't do
it in production.
https://github.com/mmucklo/memcached/blob/master/scripts/memcached-tool

Also, take a look at mk-query-digest from Maatkit. It has the ability to run
a report against memcached traffic captured using tcpdump as follows showing
histograms of popular keys, sizes etc. So assuming you're using the default
port for memcached (11211) run:

   sudo tcpdump -s 65535 -x -n -q -tttt -i eth0 port 11211 > memc_tcpdump.txt
   mk-query-digest --type memcached memc_tcpdump.txt

HTH

Thanks,
Paul
