The problem machine isn't local, but I found a local machine with a 80MB datastore.edb. Deleted the datastore.edb file and let it rebuild, it rebuilt to 33 MB. Then I deleted the datastore.edb and the logs folder, and it rebuilt to the same 33 MB size. But I'll give your idea a try next time I have face time at the machine.
On my Windows 7 x64, I had a datastore.edb, deleted it, and it also rebuilt to 33 MB. Coincidence, or result of both machines accessing the same WSUS server? The problem machine is using Microsoft's update servers.

This is a tactic utilised in one of our AU cleanup scripts which our desktop guys claim helps out.

Machine has only 512MB, but this is not a question that must be answered with "add memory" until I understand what is going on with Automatic Updates. Looking at the \Windows\SoftwareDistribution\DataStore\DataStore.edb file, that file is about 170MB, and not coincidentally, 170MB is the peak VM size I saw for both wuauclt.exe and the svchost.exe used by wuauserv. So I stopped wuauserv, renamed the datastore.edb, started up wuauserv and did a wuauclt /detectnow, and it created a new datastore.edb of the same 170 MB size as before. Looking at my own XP machine, datastore.edb is about 6 MB. And, I'm not finding much with google for "large datastore.edb" or "huge datastore.edb". The usual AU problem has been pegged CPU, but the CPU isn't pegged because of all the swapping. Anybody?
