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.
