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.
swap_pager: I/O error - pagein failed; blkno 35668,size 4096, error 5

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)?
