We seem to have found a workaround.
The problem is that our WAN only allows packets with maximum size of 1518 and 
with encryption headers we exceed that. Our other site's fix this in their 
switches before sending it out on our WAN but this is apparently not 
supported in the switches on my two problem site's.

So the fix was to lower MTU on my three Realservers to 1400.
I had to reboot my LVS server to free the hanging FIN_WAIT's, I tried to just 
unload the modules but it just hung the rmmod command.

Thanks and regards from Sweden.
