[ckan-dev] Problems uploading files in CKAN

Thu Dec 5 15:28:58 UTC 2019

Hi all, 
to upload large files (>4GB) through the api we have configured in our nginx 

client_max_body_size 15G; 
proxy_buffering off; 
proxy_connect_timeout 1200; 
proxy_send_timeout 1200; 
proxy_read_timeout 1200; 
send_timeout 1200; 
keepalive_timeout 60; 

let me know if this solves the problem.

Hello Andrew, 
thanks for the quick response. We have the max_resourse_size set to 10GB 
and we have the client_max_body_size in nginx set high as well. What we 
see is that sometimes ~500MB is transferred, sometimes, 3GB. All 
different amounts of data are transferred before the web interface 
claims that the transfer has completed when it hasn't and the web 
interface page appears to be frozen (at least the Add button is inactive 
which suggests that some part of CKAN assumes the upload is still 
ongoing). 
many thanks, 
adil
