If waiting long enough (about 5 min) it continues working but throws an already-locked-error for about 50 files and then continues locking the missing ones correctly.

On the SVN IRC channel I've been pointed to this known JIRA issue by
stsp: https://issues.apach​e.org/jira/browse/SV​N-4557
This could be the problem you are facing.

The underlying change between SVN 1.8 and 1.9 here is that 1.9 can
produce an http-header section which is much larger than it would be
with the 1.8 client. That however depends on some changes in TSVN and I
can't confirm whether that really is the case (maybe someone else can do).

For instance if SVN 1.9 would introduce a new API supporting the
multi-lock-case and TSVN 1.9 makes use of that (while TSVN 1.8 would use
the older SVN API) the net result is that with 1.9 you run into the
header-issue described in SVN-4557 while with TSVN 1.8 you wouldn't.

Given that you state you don't have any issues when not using the
SSL-tunnel, I could imagine that the SSL-tunnel protocol/server is
having trouble with passing on the longer http-header section in 1.9.
Maybe that's a lead helping you to find a workaround?
You could also check your server logs to see whether that's the actual
problem and where it is located (for instance for Apache 2.4 it could
report something like: Request header exceeds LimitRequestFieldSize). If
so and it's a feasible option for you, you could tweak the corresponding
server side setting.
