Interesting that you observe this on Linux, too. It sounds very
similar to what I observed on W2K, only that I had not that much
RAM. But the scenario was quite the same: sudden upsurge of
memory usage with every svn command, Apache had to be
stopped (and repos to be recovered what really may be because of
memory consumption reached the ceiling here for in rare cases I
could kill Apache soon during its upsurge and then the repos
remained ok.) It was said here on the list to be a memory problem
(just 148 MB RAM) and a Windows problem of swapping itself to
death when memory is short. However, since long I suspected that
this upsurge may happen with virtually any amount of RAM (and
the P4 Dell Dimension 4300 box is limited to 512MB anyway).

Freedom quote:
We who live in free market societies believe
that growth, prosperity and ultimately human fulfillment,
are created from the bottom up, not the government down.
Only when the human spirit is allowed to invent and create,
only when individuals are given a personal stake
in deciding economic policies and benefiting from their success --
only then can societies remain economically alive, dynamic,
progressive, and free. Trust the people.
This is the one irrefutable lesson of the entire postwar period
contradicting the notion that rigid government controls
are essential to economic development.
-- Ronald Reagan, September 29, 1981
