Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I've been getting some 500 internal server errors on my website every so often, so I had a look at the error log.

I am using lighttpd with Kloxo (lxadmin) installed. I have xcache enabled.

My error log is full of this. Any clues on what's going on?

The only possible conclusion from that log is that the CGI is dying. And from something pretty serious (signal 11 = segmentation fault). You should look at the CGI logs and see if you can debug and find what is making him die so badly.
