Hi Vincent!
There is insufficient information in your report for anyone to act upon.
Most importantly, it is unclear which component in the chain is causing
the problem. Is it SVN? Is it SSH? Is it TCP?
Please try to find answers to these questions.
You could use strace to figure out which system call programs are
sleeping in, e.g.: strace -p 48724
You could try to get some information out of SSH? Perhaps the sshd
server logs contain clues?
On the client side you can do this: export SVN_SSH='ssh -q -vvv --'
and try to reproduce the problem. Maybe the SSH client will print
something useful when the problem occurs?
