E.g. if they post login credentials. Of course, they'll get the error page, but then you have confidential data in your logs and now you have to protect highly confidential info, at least if you're in europe.It is possible to configure the web server not to log POSTed info.
Per default most webservers (Apache, nginx, etc) won't log POST variables, GET variables will be logged (as they are part of the query) but those should not contain any PII. Greets, Jeroen
