Comment (by teor):

 dgoulet and I spoke about this on IRC last week.

 I can't seem to replicate the exact behavior described in the logs above.
 But I can bring down the hidden service ("the hidden service is not
 available") with 60 client connections, repeatedly connecting and sending
 a megabyte of data. (The chutney test sends random data from client to
 exit/hs and verifies it reaches the other end intact). Unfortunately, 60
 tor instances is close to the capacity of my machine, and it tends to
 bring down applications, essential system services, or networking. So that
 makes it hard to confirm that the HS is going down because of the clients,
 and not just general overload on the machine.

 One of these days, I'll set up a virtual machine or VPS, but until then,
 I'll try and get these chutney changes into a state where I can release
 them.
