DDR2 controller local_ready goes low

[Altera_Forum]

I couldn't figure it out why the local_ready goes low after many write or read cycles. I checked and the proper_beats_in_fifo = 0. Does anyone have the similar issue with the DDR2 controller?

I've checked and am not sure if that the case as I don't as proper_beats_in_fifo = 0, not 1 as described in there.
