freebsd swap pager io error

Droplet is freebsd 10.1. When I use the reboot command, the VPS doesn't always reboot. It hangs up at a point with the error message:
swap_pager: I/O error pagein failed; blkno 265872, size 4096 error 5
cpuid = 0
KDB: stack backtrace
....
Automatic reboot in 15 seconds - press a key on the console to abort
--> press a key on the console to reboot,
--> or switch off the system now.

All I have is a screen capture. I'm not sure where to grab the log. The automatic reboot never actually happens. I have to press a key. Clearly this won't do. If the system crashes, I need an automatic reboot.

Now if I use the power cycle feature in the droplet control panel, the system boots fine, well nearly all the of the time.

Doing a search on the forums, my problem seems to be unique, but freebsd is a recent addition to Digital Ocean, so perhaps not many people are using it.
