>Description:

I installed a new disk in my machine, run disklabel from /stand/sysinstall,
did some stuff, and run disklabel once more, for a second slice.
Then the system begun to be unstable, some things kept getting SEGVs and stuff:

Mar 16 20:53:02 spitfire /kernel: pid 149 (httpd), uid 0: exited on signal 11 (core dumped)
Mar 16 21:41:07 spitfire /kernel: pid 715 (irssi), uid 1001: exited on signal 11(core dumped)
(..)
And so on.

I had no idea what was going on until I typed swapinfo:

[21:46] spitfire:~(60)# swapinfo
Device          1K-blocks     Used    Avail Capacity  Type
/dev/ad0s1b        153472     5036   148436     3%    Interleaved
/dev/rad6s1b       204672     4968   199704     2%    Interleaved
/dev/rad4s1b       348032     4972   343060     1%    Interleaved
/dev/rad4s1b       348032     1580   346452     0%    Interleaved
Total             1054208    16556  1037652     2%

Aaargh! /dev/rad4s1b is mounted as swap twice!
I thing the system should never allow this to happen.

>How-To-Repeat:

Like I described earlier.
