well, you possibly cleared the counters sometimes in the past, so there
are no drops shown on the bundle. I can't say anything unless you send
traffic over the bundle again and observe drops. Then this output along
with a "show int" of the individual E1s could help.

Possible issues could be a large differential delay on the links (i.e.
the rtt on the individual E1 differs greatly) which causes problems in
the re-assembly, but this is just a wild guess..
