Bug Description
At the codeathon I had a discussion with Dirk about ca reconnect times in R3.14. The issues is that CA takes a long time to reconnect if the IOC is turned off for a long time and there is a large channel count - on the order of 1000 channels. I see this constant in udpiiu.h which is related to this issue.

It also appears that bug 541358 might be a related issue?

Dirk comments that if the channel knew its address in a previous connection then it could get a faster search interval boost when the beacon from that IOC was seen.
