Hello Nginx-ers,
I had a problem with uploading large files to a FastCGI (Django) process behind nginx. Nginx crashes when running under Solaris 10 (SunOS 5.11 snv_67 i86pc i386 i86pc) and nginx 0.5.35 compiled without any special modules. I also tried nginx 0.6.29 with the same problem.
The problem is that when I upload a small file, it works fine. But when uploading a large file (> 1Mb) I got 413 request too large and so I upped the client_max_body_size parameter in the config. When I upload, I get a blank page back, with a message like this:
2008/03/25 08:03:15 [warn] 3176#0: *5 a client request body is buffered to a temporary file /tmp/nginx/0/00/0000000000, client: 75.75.25.21, server: mojipage.com, request: "POST /account/avatar/? t=1206428905 HTTP/1.1", host: "mojipage.com", referrer: "http:// mojipage.com/account/avatar/?t=1206428905" 2008/03/25 08:03:24 [notice] 3175#0: signal 18 (SIGCHLD) received 2008/03/25 08:03:24 [alert] 3175#0: worker process 3176 exited on signal 11 2008/03/25 08:03:24 [notice] 3175#0: start worker process 3184
Here's a debug log that I correspond to one of these attempts:

Any pointers would be appreciated.
You should enable core dumps for setuid processes (nginx calls setuid() to change unprivileged user) and then run
gdb /path/to/nginx /path/to/core
bt
quit
