>Could the files be still held open by an antivirus programme?
The only folder that should/could scanned by an online filesystem scanner
is base/virusscan if the option (FileScan) is used and the scandir is set
to this folder.
Scanning any files inside the ASSP directory (except above) is very wrong
and will cause in an unexpected behavior of ASSP !!!!
OK - let's look in to the code - orderedtie : sub flush():
close I or &main::mlog(0,"error: orderedtie
is unable to close I - $!");
close O or &main::mlog(0,"error: orderedtie
is unable to close O - $!");
unlink($f) or &main::mlog(0,"error: orderedtie
is unable to delete $f - $!");
rename("$f.tmp", $f) or &main::mlog(0,"error: orderedtie is unable to
rename $f.tmp to $f - $!");
$this->{updated}={};
If any file is opened by any application, the filter driver of the
scanengine will see this - and keeps it in 'mind'.
It does not matter, if the file is realy changed (depending on the
scanengine).
If the file is closed - the filter driver locks the file (for any
operation) until the scanengine has finished scanning that file. The
realy good scanengines blocking the close-action
until the virusscan has finished - but this is not done by all
filescanners.
The code sequence close I -> close O will be done in microseconds and
if the file is still locked by the filter driver, the unlink operation
will fail in the next microseconds.
The standard process/thread cycle time in Windows is one millisecond (1000
microseconds). This is the time, that a process can run without being
interrupted by the kernel
except if the process is doing any IO (open,close,read write). What I want
to explain is, this code sequence must fail in most cases, if an online
filescanner is scanning the file in the ASSP directory!
You may say, ASSP should solve this problem. Yes, we can do this by
looping the unlink (or delaying for some time) and the rename until
success. But this could cause in unwanted wait time or stuck ASSP, if the
file permission is realy bad (ASSP will never be able to delete the file).
Except the ASSP directory from the file scanner is much more easy.

running 15.1.2(1.1.09), which did all the checks on file and folder
permissions (no problems, but would not want to run that every time -
takes
a long time to start), the black and white box are now working, but the
other caches are still not deleting the tmp files.
Could the files be still held open by an antivirus programme?
