1941 Zone Firewall Session drop

Hey,

on a Ciso 1941 with configured zone-based firewall i get these messages in my log:

%FW-4-TCP_OoO_SEG: Deleting session as expected TCP segment with seq:3246849355 has not arrived even after 25 seconds - session 192.168.100.104:55877 to 95.100.32.170:80 on zone-pair ccp-zp-in-out class ccp-protocol-http

when trying to access http-sites like cisco.com and the site stops loading.

google.com is working proberly, so it seems to be when a "large" amount of data is transferd. I've got a 50Mbit DSL Connection - so this should not be the problem...

any ideas?

greets,

Andreas
