Incorrect data from ResultSet (2 replies)

Hi, while I was doing a stress testing on our Mysql server, I was surprised that sometimes I am getting incorrect data and this is happening randomly, My select is: Select ID, DATE from LEDGER Where DATE >= '2011-09-23')

I was surprised to get a row from with date = 22/09/2011 00:00:00
but if I executed this select another time right after the old one I got the correct values where date >= '2011-09-23';

Note: I am using the latest mysql server 5.5.16, and latest connector/J version 5.1.18, and Innodb as our storage engine.

does anyone have an idea... thanks
