Actually in our case there is no timeout and no waiting, error is returned
immideatly / instant also the reconect according to php profillers (xdebug)
timing costs only just 0.00(x) ms.

Besides we are running 4 MC servers now (with the PECL php extension which
distributes the items + one dedicated server just for sessions) without any
downtime for more like a month (before the planned shutdown they had like 6
month uptime).

I dont see it as a major problem (cause the simple workaround fixes it) just
wanted to confirm that such issue with the "Unknown error" exists.
