Hi,
did you increase the sequence cache? The default is 20, you should set
it up 500 , if my memory serves me well. Could be 100 too.
Just consider that you can have holes in the sequence if a rollback aplies.

From above it seems like plan_line_id 2 is running long .
Below is sequence definition :
