It somehow could be true what you say as I run tor on a machine with
really really really small RAM (128MB) as I don't 'shit' money as a
pupil to afford a bigger server.
I use Munin to monitor the server and it says that tor last used 80MB of
the RAM and then the graph stops at around 3PM so it might have been a
system or host related issue that tor stopped working this time.

This is what it mostly looks like...
dmesg doesn't show me anything related. (I never had to use it though -
It looks like it stops when the system reboots?)

As I currently can't just give it more memory, would it help to reduce
the bandwidth?
At the moment I have
