Which would explain the "missing" backup numbers... possibly. I think if 
you get an error, then you will end up with a missing backup number, so 
you won't have consecutive backup numbers (even if backups haven't been 
expired).

Can you run dmesg, and see if you have any lines like this:
[11613050.504117] rsync_bpc[7279]: segfault at 7f9ee5c7e428 ip 
00000000004473af sp 00007ffc3d7bdf80 error 4 in rsync_bpc[400000+75000]

There seems to be some bug in rsync_bpc, I was working on tracking that 
down last week, but my C programming is rather limited, so I'm stuck. 
Hoping someone else on the bpc-dev list might be able to assist. 
Otherwise, I might try one of the online programming forums to see if I 
can get some assistance there.

Regards,
Adam
