Dave thanks for the input. My dba tells me that the SQL Server cluster is an active-active so your were right in that aspect. Do you know why the queries would get queued up after a fail-over? Is there any way to force the connections to be killed maybe from the database side to force CF to recreate these?

No, I think you're right, if your SQL Server cluster is set up as
"active-active". You should be addressing the cluster itself, not any
individual server in the cluster.

You might consider shortening the time a database connection is maintained.
Maintaining connections does make a pretty big difference with SQL Server,
in my experience. I'd also be concerned if one of your database cluster
members is failing frequently, though - I think that SQL Server's clustering
ability is more useful for load-balancing than it is for failover.
