These concerns have been ignored too long. Yes, absolutely correct. Logs or tempfiles filling up /var are a problem, and in the gotweb application Tracey and I created it is indeed possible for requests to trigger large tempfiles. We need to look at that and come up with a better solution. We could check whether httpd/slowcgi could help with this somehow and try to come up with something that works for any application and not just ours.
