Hi everyone.

I have NGINX installed in front of an Apache with mod_dav_svn to access my Subversion Repositories via WebBrowser and with SVN-Clients.

Adding and committing small files is working well.

But when I try to add/commit a large file (files with ca more than 100 or 200 KiloByte) I get an error.

The NGINGX-ErrorLog says:
2009/09/14 01:02:06 [notice] 3596#0: signal process started
2009/09/14 01:02:30 [alert] 3597#0: *75 sendfile() failed (38:

host: "svn.my.synology-diskstation.de"

The error messages of the Tortoise SVN Client:
Error: Commit failed (details follow):
Error: PUT of '/repos/Paper-2009-SEISCONF/!svn/wrk/cf98065e-f6ff-bd45-be26-ba027b7b69bc/Einfuehrung_Richtlinien%20%5BSchreibgesch%C3%BCtzt%5D.pdf': 502 Bad Gateway (https://svn.my.synology-diskstation.de)

The nginx.conf part for svn:
server {
listen 7080;
server_name svn.my.synology-diskstation.de;
rewrite ^(.*) https://svn.my.synology-diskstation.de$1 redirect;
}

proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Destination $fixed_destination;
proxy_pass http://127.0.0.1:2080/repos/;
}

Also in th http{} section of nginx.conf the following is set:

include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 33;
log_format main '$http_x_forwarded_for';
#log_format main '$request_uri - $server_addr - $server_port - $remote_addr - $remote_port - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';

access_log /opt/etc/nginx/logs/access.log;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;
client_max_body_size 65M;
client_body_buffer_size 128K;
#gzip on;


Has anyone an idea whats wrong?
Only files with size smaller than 100 KiloBytes can be added/committed to the SVN Repository.

Thanks in advance, Helko
