Hi, when I upload a file (big or small) I get this error line in error.log: a client request body is buffered to a temporary file /usr/local/nginx/client\_body\_temp/0000000075 The error log marks it as warning. During the upload of a big file I expect to find the above mentioned file in the directory, but it’s empty. Any idea? Thnaks, Andrea – Andrea S. - Netbuilder S.r.l.

Hi, but nginx should remove the file only after the upload has been completed.

No. File is unlink()ed once it’s created, and nginx will work with it via an already opened file descriptor. This way temporary file is automatically deleted once corresponding file descriptor is closed, even if something goes completely wrong (e.g. nginx is killed with signal 9).
