Set request fails after restarting the server

What version of the product are you using? On what operating system?

I am using spy memcached 2.9.1.
Memacached servers are hosted on:
Redhat5.3 x64 Base Linux Build v1.7

Steps to reproduce the issue:
1 Spymemcached client connected to single memcached server.
2 restart the server
3 send a set request

Actual Result : Set request fails returning false 
Expected Result: client should successfully connect to client and set request 
should be successful. 

Note: Only the first set request is unsuccessful, subsequent set request 
executes properly.
