Hi Doug,

Today we find a strange problem in one Range Server's log:

$ grep 'Reporting.*sir_ip_index' RangeServer.log | lcat
[...]
Tue Dec  2 04:37:42 2008 INFO Hypertable.RangeServer : (/home/pp/src/
hypertable/src/cc/Hypertable/RangeServer/Range.cc:559) Reporting newly
split off range sir_ip_index[116.17.176.112..116.217.10.39] to Master

Tue Dec  2 10:24:11 2008 INFO Hypertable.RangeServer : (/home/pp/src/

Wed Dec  3 04:07:42 2008 INFO Hypertable.RangeServer : (/home/pp/src/
hypertable/src/cc/Hypertable/RangeServer/Range.cc:559) Reporting newly
split off range sir_ip_index[116.217.49.1..116.217.49.1] to Master

The second and fourth lines indicate that two ranges with the same end
row are split off, so they share the same row key in METADATA  table,
and the latter overwrite the former's METADATA record. In this way
rows bigger than 116.217.10.39 and smaller than 116.217.49.1 become
unreachable.

It is strange that the last split contains a range with the same start
row and end row. We reviewed all related code but couldn't find any
possible reason why this could happen. Do you have any idea?

We have multiple access groups in this sir_ip_index table.

Thanks

Donald
