Looking at http://common-lisp.net/cgi-bin/awstats.pl I see that common-lisp.net is one of the main visiting domains of common-lisp.net. In fact, it's the main downloader: ~100GB.

It's probably the checkbot crawler which does this, maybe because it's downloading all variants of output being generated by a cgi script or something. That would also explain why it keeps filling up the /tmp volume. The question would be: which cgi script, so we can prevent this behaviour...

Bye,

Erik.
