Unfortunately, I can report that the repeated tunnelling problem is NOT
fixed in 1.1.7.

I'm attaching the output of cygcheck -svr.

I also have a 6 MB strace output which I'm not sure I should attach here
(and before that I would have to delete the passwords and all... very
tedious to find).

The place where I first see a symptom looks like this (this is in the 20th
tunnel on this ssh; I didn't get a 21st tunnel -- there was another ssh
running in parallel, though, with the same number of tunnels opening and
closing, so I probably got a total of 38 tunnels opened and closed before
this happened on the 39th):
  201 -198454162 [main] ssh 711307 select_stuff::poll: returning 1
  189 -198453973 [main] ssh 711307 select_stuff::~select_stuff: calling
cleanup routines
  186 -198453787 [main] ssh 711307 socket_cleanup: si 0x46A27D8 si->thread
0x150
  188 -198453599 [main] ssh 711307 socket_cleanup: connection to
si->exitsock 0x148
  438 -198453161 [main] ssh 711307 __set_winsock_errno:
socket_cleanup:1287 - 10055 (WSAENOBUFS) -> 105
  202 -198452959 [main] ssh 711307 socket_cleanup: connect failed
Of course, I have no idea whether that is any hint.

Gruesse, Carsten
