When I test an example from php5-imagick package
(/usr/share/doc/php5-imagick/examples/resize.php)
apache2 "eat" a lot of disk space (a bug ?) from tmp
Output from lsof

COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
apache2 10673 apache 11u REG 3,2 280080000

ls /tmp/magick-XXuayBEU
ls: /tmp/magick-XXuayBEU: No such file or directory


After restarting apache2 all things get back to normal, occupied
space is released.

No. This is not a bug. This is exactly the behavior I was talking
about. The temporary file is created and then immediately deleted. So,
it still takes up blocks on the file system, but du has no way of
counting those blocks since the file is "gone", but it is in fact still
there since an open file descriptor exists to it.


Good explanation.
