Hey Justin,
Thanks for your reply. I ran the pstree -p command like you suggested.
I had to do it on my desktop pc though because the stripped down linux
i'm using doesnt have pstree. I get the same problem on my desktop pc
though. Here is the output.
├─lighttpd(27656)───main.py(27657)─┬─{main.py}(27658)
│ ├─{main.py}(27659)
│ ├─{main.py}(27660)
│ ├─{main.py}(27661)
│ └─{main.py}(27662)
I also tried running the main file using the built in development
environment.This is what I got:
init(1)─┬─/usr/bin/termin(6998)─┬─bash(7002)
│ ├─bash(7700)───telnet(28882)
│ ├─bash(9006)
│ ├─bash(10385)───python(29384)─┬─
{python}(29385)

{python}(29386)

{python}(29391)
│ │ ├─
{python}(29392)
│ │ ├─
{python}(29393)
│ │ └─
{python}(29394)
To me it appears that web.py is calling the multiple instances and not
lighttpd?
Here is the lighttpd.conf file anyway:
server.modules = ( "mod_fastcgi", "mod_rewrite", "mod_access" )
server.document-root = "/mnt/0.4.3"
server.port = 9000
fastcgi.server = ( "/main.py" =>
(( "socket" => "/tmp/fastcgi.socket",
"bin-path" => "/mnt/0.4.3/main.py",
"max-procs" => 1,
"bin-environment" => (
"REAL_SCRIPT_NAME" => ""
),
"check-local" => "disable"
))
)
url.rewrite-once = (
"^/favicon.ico$" => "/static/favicon.ico",
"^/static/(.*)$" => "/static/$1",
"^/(.*)$" => "/main.py/$1",
)
I execute lighttpd with lighttpd -f /etc/lighttpd.conf
Any thoughts?
Cheers,
Brendon
