Hello, I hope all is well. I am hoping someone can help me with a
problem that I am certain is user error?
The configuration details below work in all my other environments
including integration, development and qa. However, the production
servers give the following error:
unable to find server during initialization.
When I telnet to the memcached box from the server having the problem
and run ‘stats’, I get
STAT pid 16136
STAT uptime 7398638
STAT time 1275059978
STAT version 1.2.8

Below are the configuration details and stacktrace:

config.gem “memcache-client”, :lib => ‘memcache’
