One more thing: if you still have freezes, please check that it's related to socket, by using gdb on running weechat-curses process.

I think the problem is fixed: the socket is now in non-blocking mode (for both SSL and non-SSL servers).

I am unable to reproduce the problem, so I need your help to test. Please tell me during long usage if the problem seems fixed or not.

After /upgrade, the SSL connections are lost and servers are reconnected, so the sockets will become non-blocking. For other servers (non-SSL), please try to /reconnect the server, then the socket will become non-blocking. Tests are welcome for non-SSL servers too, to check if there is no side effect with the fix.

Thank you for your tests!

WeeChat was hung until killed when the server to which I was connected (via SSL) was null-routed. Backtrace is below (no symbols and such, but hopefully this is sufficient).
