DbProxy
- When the connection to the back-end database server fails, a client connected through a proxy appears to hang. This is because the default settings on the client side will retry the connection every five minutes for up to one hour. For the HLT, we need to change these parameters to something more reasonable (that makes the system succeed or fail immediately).
