Your system does not have enough memory to run the compilation job, so you are thrashing it severely.

Well, not much is running, and I have recently built a new kernel and world in less time than it takes to get this one port upgraded. I think there is something else amiss.

You can try increasing the timeout by editing the relevant kernel
source, but if it's failing to reply to the I/O after 30 seconds then
something is drastically overloaded on your system.

kernel debugging: seeing swap issues in 7.0
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
Waiting (max 60 seconds) for system process `vnlru' to stop...done
Waiting (max 60 seconds) for system process `bufdaemon' to stop...done
Waiting (max 60 seconds) for system process `syncer' to stop...
Syncing disks, vnodes remaining...1 0 0 done
All buffers synced.
swap_pager: I/O error - pagein failed; blkno 35668,size 4096, error 5
panic: swap_pager_force_pagein: read from swap failed
Uptime: 14h20m56s

Dumping 37 MB: 22 6
#0 doadump () at pcpu.h:195
195 __asm __volatile("movl %%fs:0,%0" : "=r" (td));
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)?
