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...
last pid: 26893; load averages: 36.05, 40.55, 47.01 up 0+04:29:07
513 processes: 9 running, 503 sleeping, 1 zombie
CPU states: 21.3% user, 0.7% nice, 30.0% system, 10.7% interrupt, 37.3% idle
Mem: 196M Active, 204M Inact, 83M Wired, 17M Cache, 61M Buf, 1152K Free
Swap: 600M Total, 17M Used, 583M Free, 2% Inuse, 232K Out
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?
