:I upgraded 2 of our servers from 4-releng around 4.1.1-release to one that
:cvsup on Dec 7. Before the upgrade, the systems were running at load around
:2. After the upgrade, the load went to over 40 just after few hours of
:usage. Here was some data from top...
513 processes? What are you running on the machine? 'ps axl'
By the feel of it I'm guessing a news machine, in which case it could
simply be catching up on the feed.

:The one thing I noticed was the system started swaping constantly, even
:though the Swap Used did not go up. Also, the system still had 204M Inact.
:No Swap Used before the upgrade.

:I did some search on the mail lists and saw a long thread in hacker related
:to vm_paging, but I could not find any conlusion to that thread. I did not
:see any MFC, other than a vm issue that needed to turn on by sysctl, that
:looked might be related. Any insight to this problem?
