I recently loaded a pair of Asa 5520s in a ha configuration. All rules VPNs and svc are working fine. Ever since the implementation users are complaining that websites are not loading correctly. The formatting is goofy and red x will appear over some pictures. If the user hits f5 the page comes up fine. The old firewall platform did not have this problem. All packet inspection and tie outs are default. Running 8.2(5). Any ideas? I have been troubleshooting with Cisco for days. This issue is very sporadic but seems to happen when the network is under load.

Would you please send me your Cisco Ticket on a private message?
The connection is over the SVC or regular traffic across the ASA?
Another important question is for how long does the problem lasts?
Have Cisco taken packet captures when the problem was happening and when everything is normal?
Are there any other devices on the network that may be affecting this connection?
