Sounds familiar. Probably your pre-commit hook is taking too long when
you commit the entire source tree. I had that problem as well, and
took special care to optimize my pre-commit hook, so it can handle
very big commits. SVN itself does not have a problem with very large
commits, but pre-commit hooks (and post-commit hooks) can cause
trouble if they take too long.

For instance, if your pre-commit hook does an "svnlook changed" or
"svnlook dirs-changed", and then does some check for every
path/directory that's being changed, that probably scales linearly
with the amount of files/directories that are part of the commit. If
every check takes 50 ms, and there are 1000 changes, your hook will
take 50 seconds.

If the pre-commit hook takes too long, the client gives up, and
terminates the connection (by default after 30 seconds, I think). You
can increase the client-side timeout [1] to avoid this, or make sure
your pre-commit hook is fast enough.

Alternatively, if this kind of commit is very rare, and you're sure
that it is valid for the pre-commit checks, you can temporarily
disable the pre-commit hook (or part of it, or only if $USER=<you>),
to make it go through. Or commit in pieces, like you did.

It's an interesting exercise for the reader to add some debug/timing
logging to your pre-commit hook, to see how long it takes. See also
