It means that your /var filesystem is nearly full. The kernel is now
trying to maximize the amout of free full blocks on the filesystem.

The element fs_optim specifies whether the file system should try to min-
imize the time spent allocating blocks, or if it should attempt to mini-
mize the space fragmentation on the disk. If the value of fs_minfree
(see above) is less than 10%, then the file system defaults to optimizing
for space to avoid running out of full sized blocks. If the value of
minfree is greater than or equal to 10%, fragmentation is unlikely to be
problematical, and the file system defaults to optimizing for time.

Some other good reads would be tunefs(8), newfs(8), and the mailing list
archives.
Thank you Chris and Jens for your replies!
A full file system on /var triggered it?
# df -k
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/ad1s1a 65470 40452 19782 67% /
/dev/ad0s1e 2030062 801262 1066396 43% /usr
/dev/ad1s1e 35230 17770 14642 55% /var
procfs 4 4 0 100% /proc
It doesn't look full to me.
Best regards,
Paul
