Are you running any other programs with your bridge that might be
using your memory?

I have a exit relay that is running the same cpu and ram and have
never been up over 1G at any time.

I also run a bridge, with at times other things and my total ram there
doesn't even come close to 1G.

My guess is you may have some other programs running in the background
or other programs you may be using that is causing the ram to rise and
using up your resources.

Which version of Tor are you using, and what package did you obtain it from?

On a Unixoid operating system, recompiling Tor with the
--enable-openbsd-malloc configure option would probably help.  But
that code isn't currently Windows-compatible.

Is it possible that someone using my bridge dropped something into my
system?

Thanks Jude. I don't think anonymity has been compromised, while running
the bridge I haven't used the client, being busy with other things. I
haven't had time yet for *nix. I've run VirtualBox for a couple of
years. (For the devil of it I've run Vidalia successfully in Win2K in
the VM, and also off a flash drive, but don't have any reason to think
those two ways would be any more secure than running off the Vista host
machine.)

Thanks too for Jon's  Robert Ransom's replies. I was running no extra
apps when this problem started. I'm using TBB 2.2.35-7.1, it's clean.
Looking at processes, I see way too many new svchosts. I'm running
tasklists in a batch file for the next few days to see what the svchosts
are carrying  what changes as the memory use rises. So far no malware
reported by AVG, I'll run a full system scan tonight. After that I'll
recheck my local  modem/router ports. The bridge has been carrying
traffic from up to 14 countries according to the bandwidth usage,
sometimes it's quite heavy. AFAICT the message log doesn't show anything
amiss. - eliaz | gpg ID: C3E1E38D

 Weell, there's your problem.
 Your using windows.
 
 That right there is enough to kill any anonymity even if your using Tor.
 Personally I have seen Windows machines become infected when:
 It wasn't being used except once a week,
 The user was one who had a reasonable knowledge of security (Me)
 Anti-Virus (actually did not detect it..)
 Incoming connections where heavily blocked (related,established)
 
 
 You have plenty of RAM, run a virtual machine (virtualbox works great)
 install debian on it (my personal choice) no gui.
 give it 256MB of ram, no swap. (that's a LOT for this setup...swap off
 so that instead of freezing it just kills the process)
 run Tor inside the VM.
 
 Voila, ram usage will now NEVER exceed the size of the VM, and it's
 relatively easy to set up.
 CPU usage for the VM will also be really low.
