Right now (04:50 GMT) my node is connecting to yours and getting zombie
connections each time. The socket isn't returning an error, just zombie
without notice. If you're running the linux build right now, it would
be interesting to see what the log says on your side.
test3:
I've added specific code to detect zombie sockets. It'll detect if the
socket hasn't sent or received any data within 60 seconds of connecting,
and detect if data is queued to send and hasn't sent for 3 minutes.
I think I may have weakened the reconnect speed in test2. In test3 I'm
making it more determined to reconnect quickly.
I added checking to track whether other nodes received your generated
blocks. If none did, it'll warn you in the description:
"Generated - Warning: This block was not received by any other nodes and
will probably not be accepted!"
The status can go to "#/offline?" for blocks or transactions you create
if they don't get out to any other nodes.
With all this, it should be impossible not to notice as soon as it
screws up. It should hopefully disconnect all the zombie sockets.
After that, whether it's able to make some good connections, or sockets
is completely hosed and it stays at 0 connections, I don't know.
If this doesn't work, I guess I'll look at the sourcecode of some other
P2P apps like BitTorrent and see how they deal with this stuff. Maybe
there's some magic flag or procedure to bash the sockets system back to
life.

test 5:
I added MSG_DONTWAIT to the send and recv calls in case they forgot the
socket is non-blocking. If that doesn't work, there's now the catch-all
solution: another thread monitors the send/recv thread and terminates
and restarts it if it stops. It prints "*** Restarting
ThreadSocketHandler ***" in debug.log, and an error message displays on
the status bar for a while.
Before terminating, it tries closing the socket that's hung. If that
works, it doesn't have to resort to terminating.
I ran a test where it terminated the thread about 1000 times without
trouble, so it should be safe. The terminate on linux is
pthread_cancel, which throws it into C++'s exception handler.
The thread calls we were using didn't have terminate, so I created our
own wrappers in util.h to use CreateThread on windows and pthread_create
on linux, instead of:
_beginthread is windows only and lacks terminate
boost::thread is really attractive, but lacks terminate
wxThread requires you to create a class for every function you might
call (yuck)

I created a forum on Zetaboards, InvisionFree's new site that they're
migrating to.
http://s1.zetaboards.com/Bitcoin/index/
I made an admin account you can use to upgrade your own account to admin:
u: admin
pw: B98VzUUA
BTW, the admin pages have a huge blank space at the top, you have to
scroll down.
It doesn't support SSL, but none of them do. I replaced the ugly
default orange and blue theme with the Frostee theme, which was the only
decent looking theme I could find after extensive searching. Searching
for themes is futile, there are thousands of rubbish themes. It turns
out the solution is to look at button sets instead
(http://resources.zetaboards.com/forum/1000328/)
I only created two subforums to begin with. I'll create new ones as the
need arises. I like to start with a flat namespace until there's enough
items to justify subsections. Technical Support makes sense as a
separate section to get that stuff out of the main spotlight so our
dirty laundry isn't in everyone's face, and to make people feel more
free to report bugs there. Mostly only devs and people checking on a
bug need read the Technical Support section.
