问题
I'm using the ServiceStack Redis Client and I was hoping that I could get a clarification on what might cause the following error ... "Unable to Connect: sPort: 50071"? I'm using the "PooledRedisClientManager" object for connections. Thanks for any assistance.

IF YOU ARE USING A SELF HOSTED REDIS SERVER AND USING THE Service Stack Redis Client THEN BUYER BEWARE
As of 9/23/2015
Service Stack does license validation in the client code (rather than the server). If you are ripping through a lot of messages 6000+ an hour you will get. The resulting error is
Unable to Connect: sPort:
However, it is not handling their custom LicenseExpection and exposing the error correctly. The error would be something like this:
The free-quota limit on '6000 Redis requests per hour' has been reached. Please see https://servicestack.net to upgrade to a commercial license or visit https://github.com/ServiceStackV3/ServiceStackV3 to revert back to the free ServiceStack v3.
I doubt you have imposed such a limit on your server :-)

This could be a time out issue, try increasing it:
pooledRedisClientManager.ConnectTimeout = 1000
You need to check that you are not creating a new PooledRedisClientManager for each request / usage. You will quickly run out of ports. Use a singleton approach in a web environment.
