The new 2.4.21-20.ELsmp kernel seems to go spend all its time in kswapd when doing backup using tar over the network - is this a known problem? The problem goes away when reverting to the 2.4.21-15.0.4.ELsmp kernel. Even though kswapd uses most of the cpu the swapspace is hardly used.

This is on a Dell 2650 with a PERC4/SC RAID controller using the megaraid2
driver.

The machine runs Cyrus imapd and only tar is active during the night when
this happened.

How large of a dataset?


Bill

Typically about 140GB.


The receiving machine is an FC1 box with a FireWire card and an external FireWire disk - it is a lot cheaper and more convenient than tape.
