I could only get before-firewall-that-propably-screws-things-up dumps.
I will surely do that too.
Locally it's not affected.

With tcp_windows_scaling to 1 and tcp_default_win_scale to 0
everything seems normal again. Dumps of this will follow soon.

Also, to fix the firewall we need to prolong the licence to get support to
apply the hotfixes or to do a kernel upgrade or whatever would be
necesarry. For this I will have to wait a bit :-(
