Output buffer limit exceeded: operation stopped

I am trying to read a csv file of 31 Kb in my module.php and when i add an instance of the module it shows the output exceeded limit error.
What can i do to solve this ?

It must be an error in your script. The output buffer is limited to 1024kb :grimacing:

Please check if your loop ist making an error. Maybe try limiting the loop to just s few iterations.
