 So dhcpcd is logging the message sent in the DHCPv6 reply to say:
 No addresses available for this interface.
 In a stock config, dhcpcd will NOT request DHCPv6 unless a RA is found 
 with either the Managed or Other flag set.
 dhcpcd will obey this flag.
 So I'm guessing the RA is saying a Managed address is available but the 
 DHCPv6 server is saying otherwise - literally because dhcpcd doesn't 
 contain that string, so the DHCPv6 server sent it as a message.
 This causes a DHCPv6 failure, so it aborts. However, the process will 
 restart when another RA is received with another DHCPv6 instruction.
 In other words, dhcpcd is only spammy with a badly configured network 
 and is no different from a DHCPv4 server which NAKs the address you 
 request based on the address is originally offered.
 I don't see anything to fix in dhcpcd here.
