(I'm assuming the date then was 18 Jul 2006, date of report.)
Note that the access time is just one day ago (2006-07-17 vs. 2006-07-18).
>From the manpage:
tmpreaper dates files by their atime, not their mtime, unless you
select the --mtime option. If files aren't being removed when ls -l
implies they should be, use stat(1) or ls --time=access to examine the
file's atime and see if that helps to explain the problem.
Additionally, tmpreaper can be instructed to also check the ctime
(inode change time, which is updated e.g. when the file is created or
permissions are changed). This is primarily useful when tmpreaper is
used to clean up directories that are accessible as a Samba share; DOS
(and Windows) PCs preserve the mtime and the atime when copying to a
new file, so that it appears that the newly created file is old.
tmpreaper will remove such files is the atime is beyond the removal
time, even though they were just created. This is avoided by using the
--ctime option.
Hence, using the --ctime option will _prevent_ eary removal; it won't
make tmpreaper remove files _only_ due to their ctime.
Tmpreaper first looks at the atime if --mtime is not given (--ctime
doesn't make any difference here). If the atime is not "old", the file
is skipped. If the atime is _not_ "old", then, if --ctime is given, it
checks to see if the ctime is also "old"; only then is the file removed
(if --ctime is not given, an "old" atime is enough for removal).
If --mtime is given, then only the mtime is used to determine whether
the file should be removed or not. You can't use --mtime together with
--ctime.
I hope this is explanation enough?
