file copy is stuck after 4GB


Hi I am running REDHAT AS 4, file system is ext3

I am trying to copy (I have tied rsync, cop) a 17GB from from /volume1 to volume2, problem is this gets stuck after transferring 4.7GB of data

I dont see any IO errors in message log either or when I do fsck it says the file systems is clean

What could be causing this and top and iostat outputs are follows. when this the copy command (rsync, cp) is unresponsive top shows hi "wa" but iostat is not showing much disk activities as well

I'd just like to add that RHEL4 went out of regular support earlier this year.
Unless you pay extra for extended support, you should replace with RHEL5 or RHEL6.
