Does anyone know what this means?

Ive been having some freezing problems with my oscam server
The picture freezes for about 25 seconds every hour or so
Very annoying so I monitored the log file and at about the same time it happened I got this printout in the logfile

2017/01/03 22:08:16 75C1D0F0 r (reader) ice [internal] Card type: SYAV

AFAIK I don't have the card SYAV type, and have no credit with a Server and don't know what fusebyte or classD1 are

Ive edited out some info that might be sensitive (sorry if Ive posted this twice)

What does 75C1D0F0 mean?

What do these fields mean?
I looked on the oscam wiki but couldn't get any info about the log file set up

Thanks fro the reply Satman

It is a vu duo running oscam 10666.
There are 10 accounts in oscam.user

If the log is showing that readout when the card first starts then there is a problem since the card had been on all day and it suddenly gave the readout half way through the footy match?

That sounds like a good idea monkified.
What is a good alternative for the duo? I installed a campack for the blackhole image
