[Pgpool-general] failover question

Hi,
I'm running pgpool2 3.0.1 with replication mode on two postgresql 9.0.4
db servers (updated from 8.4.4). I have the 'replicate_select' and
'replication_stop_on_mismatch' both set to 'true'.
I just noticed that under psql, if I cancel a long select sql (before
any output displayed), I'll get the following message and the pgpool
failed over. I don't recall this happened with 8.4.4. Can anyone
explain why and how to avoid this ?
[sd3ops1.ops1_admin].sd3ops1> select * from file;
Cancel request sent
ERROR: kind mismatch among backends. Possible last query was: "select *
from file;" kind details are: 0[E: canceling statement due to user
request] 1[D]
HINT: check data consistency among db nodes
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Succeeded.
Thanks,
Gary
