Fixing maxvnodes seems to have sorted out the problem. Here's the top header,
in case it bears any more investigation.

last pid:  8729;  load averages:  0.16,  0.15,  0.10                           
                                                    up 0+18:24:10  11:07:00
36 processes:  1 running, 35 sleeping       0.0              100
CPU: 8040% user,  0.0% nice,  0.0% system,  0.0% interrupt,  0.0% idle
Mem: 796K Active, 27M Inact, 81M Laundry, 5631M Wired, 155M Free
ARC: 2639M Total, 643M MFU, 317M MRU, 972K Anon, 16M Header, 1663M Other
     195M Compressed, 765M Uncompressed, 3.92:1 Ratio
Swap: 

When I cut maxvnodes from 1048576 to 524288, the ARC Total dropped from 2639MB
to 1455MB over about 30 seconds. Further reducing maxvnodes brought the Total
down below the configured arc_max.

Thanks!
