Log isn't all that important. The servers tend to truncate it after
every operation. I don't think I've ever had a log that needed to be
larger than about 20MB.

You seem to have about 2.5MB in use. I'm not sure if this is peak or
current usage.

The important size is RVM data. The only way to get it is check the
logs, once every 1000 operations or so the server dumps a lot of
internal statistics one of which is 'RDS Statistics' (you can also
trigger a dump with volutil printstats).

    Number of
     Free bytes:     66a4060
     Alloced bytes:  495bc40

The numbers are in hex, but here we see clearly that on this server less than
50% of RVM data is allocated.

Then restart the server, it only re-reads the vicetab file during startup.
