I can't understand it either. It doesn't make any sense to me. It might be interesting to run cpu -h io iostats venti/checkarenas -v /dev/sdC0/arenas arena.30 and see if the problem happens then. The only thing I can think of is that when run with something proxying the 9p connection, some reads return less than the amount of data requested, and venti is not correctly reissuing the read for the remainder of the block. That's a very scary thought. The relevant function is /sys/src/cmd/venti/srv/part.c:/^prwb but it looks okay. Maybe there is some bit of code that's not calling it. Russ
