Suppose there are 50 columns. Are you executing one update statement
for each column, like

update atable
set column1 = :avalue
where pk = 99
COMMIT

update atable
set column2 = :bvalue
where pk = 99
COMMIT

update atable
set column3 = :bvalue
where pk = 99
COMMIT

.... and so on...

and you restart this cycle every 60 seconds?

Can you show the client code that executes?

Are there any update triggers on the table?
