OOM error when run all paragraphs

[Dafeng Wang]

Hi,
Today when I try to run the zeppelin with a complicated notebook, if I run them 
one by one, it works well, however, when I click on running all paragraphs, it 
will throw OOM errors in a short time, I set zeppelin’s interpreter’s memory as 
6G. any idea?
Regards,
Dafeng
