Fast shutdown simply means that clients are not given the chance to finish their running transactions before they are disconnected, which is totally safe (those in-flight txns get rolled back). Given the complaints in the log about SSL, I tend to suspect the software update more than anything else…

Depending on how many of Calendar Server's dependencies are provided by your OS, and depending on how many of those dependencies were upgraded in your OS upgrade... I can imagine various sorts of breakage, although I don't have any specific ideas based on your traceback.

Are you able to bootstrap a new Calendar Server instance in the upgraded OS, for testing purposes?
