I had this happen on 2 different boxes running 2.2.5 with different mixes of drives. But not on my news server running 2.2.5 but non wide. The only difference I then see is that I also used the option AHC_SCBPAGING_ENABLE which you dont have in your stuff below. So I wonder if thats the bugger doing it.
