Subject: ptrace: umoven:

I googled 'umoven' and see that lots of people have reported
this problem, but I don't see any solution.
How do I get rid of the 'umoven' error when `stracing` system calls?

Typically:
open("/home/cat3/work/view.dat", O_RDONLY) = 4
read(4, ptrace: umoven: Input/output error
0xa1b6d000, 41884)              = 41884
read(4, ptrace: umoven: Input/output error
0xa1b7739c, 41884)              = 41884
read(4, ptrace: umoven: Input/output error
0xa1b81738, 41884)              = 41884
read(4, ptrace: umoven: Input/output error
0xa1b8bad4, 41884)              = 41884

The read actually succeeds, but ptrace doesn't like it.

Cheers,
