Andreas Bonini's questions

I am a programmer for a popular website hosted by two web servers with apache. We're in the ~1000 alexa rank range to give you an idea. I'm not a server administrator.

Only one of them (always the same one) has been having a problem that started for the first time last week: every 2-3 days, it crawls to a complete halt timing out all HTTP connections and SSH connections as well. If you are already SSH'd in typing commands is either extremely slow (20-30 minutes before they appear) or doesn't work at all.

The only way to temporarily fix the problem that we found is rebooting the server.

I noticed this in our graphs:

Every peak corresponds to the server halting, and every drop corresponds to the reboot we were forced to do.

How can I further debug this? Is there a way to see what process is using the most inodes? What would you do?

This may be a stupid question but even after reading the documentation I'm still not sure how to find all lines in a file that contain either ".cpp" or ".h".

Is there a way to do that?

For example (doesn't work):

findstr /i .cpp,.h // , == OR

I'm toying with the idea of creating a private torrent tracker website; the ones that require registration and track their users' ratio, have "credits", and so on.

Can you list some torrent trackers suitable for this? I tried googling a bit, and I found for example opentracker, but as far as I know it doesn't provide a way to give the website the information required to track ratios, etc. Also I don't see a way for the website to tell the tracker which torrents are allowed (since torrents would be created through the website).

Thanks!
