nchan lock the files in client_body_temp

[KamranBiglari]

I have an issue with nchan while I'm publishing via websocket. ( I never close the WS connection on publisher side and it's always connected ) The message size is 37k and nginx create a temp file in client_body_temp_path. I change these configuration to avoid nginx to create temp files but there is not luck.

client_max_body_size 10m; # Also to 0 
client_body_timeout 2s;
client_body_buffer_size 10m; # Also to 0 
client_body_in_file_only clean; # Also on / off
send_file on; # off as well

The temp files have been disappeared after a while but in background they are all exists since when I check the iNodes the nginx consume the inodes and files are locked! If I close the WS connection the nginx/nchan permanently delete the files and release the inodes and locks on files.

Can anyone help me to fix this issue because after a while the system run out of inodes ! @slact
