kernel debugging: seeing swap issues in 7.0

[paul beard]

I see a lot of these as my system grinds to a halt. It never crashes
(I reboot it when it gets really boggy . . .


May 23 11:41:13 stinky kernel: swap_pager: indefinite wait buffer:
bufobj: 0, blkno: 49155, size: 4096
May 23 11:41:21 stinky kernel: swap_pager: indefinite wait buffer:
bufobj: 0, blkno: 48905, size: 4096

This is the top of the kernel debug

Unread portion of the kernel message buffer:
<118>May 23 12:48:46 stinky syslogd: exiting on signal 15

All buffers synced.

I have partition-based swap and swap files I set up after gcc was
running out of memory.

Device:       1048576-blocks      Used:
/dev/ad0s2b          139              0
/dev/md0              128              0

Any ideas what I can do (besides buy more hardware)?
