java memcached client & tomcat

[David O'Dell]

Greg I appreciate your response.
We are running with the defaults:
Define the pool
<value>192.168.173.92:11211,192.168.173.93:11211,192.168.173.94:11211,192.168.173.194:11211,192.168.173.195:11211</value>
They have an equal weight.
On one host I was concerned that we have MaxConn set too low so I set it
to 100 instead of the default of 50.
<name>max_spare_connections</name>
<value>100</value>
