I have VPS which is on virtuzzo platform and I use kloxo as the admin panel! So I use about 5 proxies on my server and I can guarantee that no more than 50 concurrent connections happening at the same time as the proxies are too new. But after few days or hours apache web server stops and giving me 500 internal server errors but Kloxo is still functional and when I restart the apache or kloxo problem disappear. And switching to lighttpd is same it also giving me the same error after few time. Whats the problem? all the time when apache or lighttpd stops Kloxo can be accessible without any problems. Apache or Lighttpd doesnt stops at certain time. the time is random some times its a day some times 12 hours like that but it didnt ran more than 48 hours! Previously I had my proxies hosted on VPS server and other few of my sites (that VPS gave me the same error too). but after that I moved i to another VPS for my proxies and instaled a fresh copy of kloxo not rsync the old one! I transferred all of my proxies but but I didnt moved my other sites. After moving proxies to new VPS the error on the Old VPS gone and its not giving the 500 error now! But my new VPS with my proxies started to give this error! All of my proxies use Glype script which is very popular and not have known errors on script! And my proxies got about 300 visits per day and its not a huge amount to give 500 errors right? If you can fix this error i would happy to give you $5 via paypal there might be quick fix for this Heres my httpd.conf file Sorry the file is too large to attach on the forum so I have uploaded to megaupload http://www.megaupload.com/?d=S3MIXDFB
You would need to go through the logs to find out why the error is being thrown out. Someone will have to be able to have root access to your server to figure things out, and make changes. If you still need this done, feel free to PM me with all the required info. Chris
