what is your hardware config, mainly for disks ?
in the if I use LVM on top of ide disks some big file transfert, like 
ftp tar ..., the system hang  during the file manipulation.
when moving the same config on SCSI disk I never see this situation.

My config is soft raid1 + lvm + ext3 fs

Now this is just an example, it's like the entire filesystem stops while removing the file.  Running reiserfs ontop of lvm.  Also, when copying through ftp/smb from the server, I max on about 6mb/sec, which is far from the 12.1mb/sec avrange I've gotten out of that network card before (on a slower computer).
