mysterious hang during svn 'update'

<note: originally posted on tortoisesvn board, was referred here>

Hi,

I have been using svn for about 9 months. Everything was
fine at first but sometimes I would notice 'update' would
only get a few files and usually hang on larger binary
files. By hang I mean the update process appears to stop: svnserve -t
cpu usage is zero. The VM size of the process is only about 10mb
and CPU and memory are never more than a few %. I get no errors reported
back through tortoise.

At first I could usually retry and eventually get my whole
working copy. As size of the repository has grown, it is now almost
impossible just to update a working copy if more than 3 (~1mb sized
files) files need to be downloaded (i.e. svnserve -t always just hangs
and does nothing, no matter what). Doing a local checkout on the machine
hosting the repository does work fine though.

I have used svn 1.1.4 and 1.2 on fc3 with svn+ssh, tortoise client on
many windows xp boxes. My repository is about 250mb, with
many binary files (library and tool dependencies).

Dump/load under 1.2 didnt help, nor did migrating from bdb to fsfs.

On the client end, I am using the latest tortoise; SSH appears
functional, and McCrapee virus scan is disabled.

Looking in the docs, mailing lists, and google has yielded
few leads and no solutions... Can anyone help? If not, can anyone
recommend another scm? svn was great for a while but seems to have run
in to a wall for me.

Thanks in advance for any ideas...

Daniel
