For some unknown reason when my rMBP is idle it ends up accumulating thousands of connected AFP users if I put it to sleep while connected. Pictured below.
(NOTE: I am on 10.10 beta in the picture but it happens on 10.9 too. The server is running 10.9)

I think it may have something to do with this...
MacBook Pro with Retina display, OS X Mavericks (10.9)
The third item in your list of alerts is a notification that one of your drives dropped out. That is not normal, and Mac OS X is not prepared to work around it.
Which TMB is "out of date"? Yours? Do you do TMB on the mentioned drive?
Can you check your energy settings, if you allow backups during sleep?
And...check your certificates on the server.
Did you ever get a mail from apple that you have to renew your certificate?
OS X Server: Renewing Profile Manager's code signing certificate
"With OS X Mavericks, you receive an alert in Server.app 30 days before the certificate expires. Afterwards, an alert is shown in Server.app once a day until the certificate is renewed. The alert includes a Renew button that allows you to renew the certificate. "
This is for PM, i know, but I think ServerApp will send these alerts for all kind of certificates.
I have power nap enabled. The certificate isn't set to expire until February. I do TM Backup on one drive, but not the one that I'm usually connected to with AFP.
Thousands of connected AFP users
