KSZ8851 - RXOIS Receive Overrun Interrupt Status

Hello,
I have issue with KSZ8851
After some time of operation I receive RXOIS (Receive Overrun Interrupt Status).
 
There is no any explanation in datasheet but I suppose there are too many received frames in RX FIFO.
Every time I receive RXIS Receive Interrupt Status, I check pending frames by reading REG_RXFCTR. All the time number of pending frames is between 1-4 so it is not a problem.
 
How can I check available RX memory during operation? Is it possible?
