[cisco-voip] UC server performance and UCCX agent in reserve

[Charles Goldsmith]

For us, we are restarting tomcat on the pub about once a week.  Our
administrative interface is used pretty heavily with MACD stuff.  I've
found that if we use one of the low utilization subs, we aren't having the
issues.

We can't restart tomcat that easily due to EM usage, and yes, we have a
dedicated pub.
