Yes, I see. blktools seems to buggy, yes. But blktool outputs memory fragments that seems to come from other processes. I saw string "bash", "lled with unallocated bl" and other strings that do not appear in blktools image. Without further investigation it seems that in case of the error, soma data ise leaked from kernel to the buggy program in userspace (blktool in this case). -- Meelis Roos (mroos@ut.ee) http://www.cs.ut.ee/~mroos/
