Hi Michael,

i have an installation running with awstats and naviserver 4.99.6, using 

ns_section "ns/server/${server}/module/nscgi" 
       ns_param map     "GET  /awstats /usr/lib/cgi-bin"
       ns_param Interps CGIinterps

ns_section "ns/interps/CGIinterps" 
       ns_param .pl "/usr/bin/perl"
where /usr/lib/cgi-bin contains among other things awstats.pl
Awstats can be called via "http://yoursite//awstats/awstats.pl?config=...".
Runs smoothly.

The nscgi documentation is in [1].

Thanks, Gustaf.

I double-checked/adjusted our settings and restarted and still see the same behavior. The awstats script exists and I can run it by hand as Naviserver user. The April stats DB looks to be up to date and OK. The last update to Awstats was in 2012 and it was running fine behind Aolserver well after that date.

Any suggestions as to where to look next?

Thanks, again.

Can it be that this machine is running low on memory?

What happens, if you ran a "hello world" CGI script via NaviServer? (see example below, put "hello-world.cgi" into your global www directory).

Do you have the chance to compile the newest version of NaviServer from bitbucket [1]. I've just added more debugging aids, one can now turn on at runtime debugging of nscgi via "ns_logctl severity Debug(cgi) on".

-g

config snippet 

#
# CGI
#
ns_section "ns/server/${server}/module/nscgi"
   ns_param map     "GET  /*.cgi"
   ns_param interps cgi

ns_section "ns/interps/cgi" 
   ns_param .cgi "/usr/local/ns/bin/tclsh"

hello-world.cgi 

puts "HTTP/1.0 200 OK
Date: Monday, 06-Nov-95 17:50:15 GMT
Content-Type: text/html

<html>
<body>
Hello World
</body>

Same behavior when accessing the Tcl CGI script.

I don't think memory is the issue; Awstats ran smoothly with 1/4 of the RAM we have now and ran fine on the current hardware under Aolserver.

Next chance I have, I'll compile Naviserver and let you know what that turns up.

Thanks.

Finally had the opportunity to build the 4.99.8 release. Turned on CGI debugging (the run-time debug switch is great, btw) and ... it worked :). No other configuration changes since trying with the previous build a few days ago.

If the problem shows up again, I'll try to debugging again. For now, though, thanks for the release!

Btw, you might be interested in the WebSocket interface of NaviServer

https://bitbucket.org/naviserver/websocket

which lets you watch e.g. the error.log in a browser window (like "tail -f"); you can switch from the error.log view the logging options...
