The repository is pretty massive (GBs ...) and there seems to be quite
a few large docs (pdfs, html files) checked in. Thus a raw svn update
may simply take out the server (any tips on configuring apache/svn to
avoid this gratefully received)

When doing raw checkouts it might be an idea to them incrementally
(e.g. pick particular folders or subfolders and do svn ups on each of
those one at a time). Perhaps Francis may have useful comments here as
he knows the repository structure much better than me.

My guess here is that the server is simply being overwhelmed.

Does this occur once you have done a complete checkout. At that point
the updates should be much smaller and shouldn't make the server fall
over so badly.

Hope the above is of some use. I should also mention you could create
a local copy of the repo by syncing the backup via rsync (slowly with
b/w under, say, 30kb/s) see:


(You'll just want the ukparse subitem by the way)
