slow query log

[Ananda Kumar]

Hi All,
I have enabled slow query log.
Generally this file will have sql's which take more than long-query time to
execute and also sql's not using indexes.
But i see sql's which does not come under the above condition.
I have set the long-query time to 1 Sec .

The query takes less than 1 sec to execute and also uses indexes, but still
its recored in slow query log.
Any idea why this happens.

Thanks for your help.

regards
