I reported an issue to the OpenBSD misc@ mailing list regarding recent behaviour of spamassasin on my mail server. If you look at ls -alh output the bayes_toks file is 65.3G large, this value is confirmed by wc -c & the file lives on the /var partition. If you take a look at the output of df -h there isn't a single partition that uses that amount of space. The largest is var reporting usage at 4.3G. When the file was deleted the value reported for var dropped from 4.3G to 2.0G. Can anyone explain why the used disk space is incorrectly reported?
