Need to fix and optimize python code

There is a python script which is using elasticsearch and facebook marketing api. In the last step of script, it updates an elasticsearch index, but sometimes it freezes in ubuntu. Tried giving delays, optimizing threads etc but no success.

Need a python expert urgently who has actually worked on these two techs.
