tDBOuput - getting NB_SUCCESS great than NB_LINE - how?

[ml1662663516]

We are tDBInput from Postgres and then tDBOutput to Snowflake.

After that subjob we are using a tJava to log out:
NB_LINE
NB_SUCCESS
NB_REJECT

If NB_REJECT > 0 then we have a tWarn.

However, what is interesting is that in the tJava we sometimes see the NB_SUCCESS greater than the NB_LINE in the logs?

My understanding is that NB_LINE is the total records processed. NB_SUCCESS are successful records. NB_REJECT are unsuccessful records.

So, how could NB_SUCCESS ever be greater than NB_LINE?

Thanks for any insight!
