Hi all,

I'm not sure if this is the right list to post to, so please direct me to the appropriate list if this is the wrong one.

I'm having some problems on the latest 2.6.17-rc3 kernel and SCSI disk I/O. Whenever I copy any large file (over 500GB) the load average starts to slowly rise and after about a minute it is up to 7.5 and keeps on rising (depending on how long the file takes to copy). When I watch top, the processes at the top of the list are cp, pdflush, kjournald and kswapd.


Are there some processes stuck in D state? These will contribute to the load average even if they are not using CPU.
