It is ultimately the responsibility of the server to manage its memory and
not crash etc.  Since you can reproduce this with https, I would focus on
that since it offers better logging.  Turn on the SVN operational logging
if possible and try to find out what "commands" the server is receiving.

This is odd.  I cannot think of why the checkout process would call this.
Perhaps you have the History view showing somewhere with the Link to Editor
feature active and something is triggering that view to also make a call to
the server to fetch history?  That said, I fail to see why running checkout
and a history call at same time would be an issue for the server.
