Hi,
Sorry for typo mistake. I meant 8.0.7 (not 8.0.5). I downloaded it
yesterday. And as I said, it is still a cpu hogger and on top of it,
file corruptions occurs.
When file corruptions happens, you cannot delete the file (during an
ftp session) because the system claims that it is in used by a
active process. Only after you stop nfs and you can delete the file
on the server itself not during an ftp session. If there is file
corruption, during an ftp session, nfs displays the file name and
file size. But when you try to download it, the ftp client session
reports file does not exists and is of zero byte size.
