multiple memcached server problem with perl and c++ client

[Kabir]

hi
my problem is , i ve two memcached server running on two different linux machine.
and from another linux machine using perl memcached client updating memcached server's correctly,read from perl client is fine.
but i ve windows machine which run utility which in turn reads data from same memcached server's using c++ client
problem is c++ client some time flag the error no-data-found even if kye/value exist,i believe it is because perl anc c++ client have differnt hashing alogorithm which choose server then key.i am using follwing client libs.
could you please suggest perl and c++ client which sync with each other in terms of hashing, or other better solution but i ve to use perl client to set and c++ to read.
