PTK is related to the authentication protocol, see here
http://en.wikipedia.org/wiki/IEEE_802.11i-2004

Do you have  connection with some devices, for example mobile phones?

PTK is part of the process of a wireless client authentication
hostapd: ptk update fail,  means that there was a problem in such authentication process.

You have a real problem if you see that your connections drop, but if this is a random message, you can ignore this.
It is hard to discover who is causing that. Try to discover the exact time when it happens: while a client start up, or every day at the same our, or when you connect a new device.

It could be or not a problem: if you notice faulty wireless connection, this message is a warning, otherwise it is not a problem
