Browsers cannot access PAC files stored on the appliance when the port is 
changed in some cases 

Browsers cannot access PAC files stored on the appliance when the port is changed 
from the current value and when browsers try to access the PAC file using only the 
hostname specified in the Hostnames for Serving PAC Files Directly section on the 
Security Services > Proxy Auto-Configuration File Hosting page.

Workaround: Reboot the appliance. Or, to avoid restarting the appliance, you can 
make any change to any Access Policy and then submit and commit the change. For 
example, you can create an Access Policy, submit and commit the change, and then 
delete the policy and submit and commit your change again.

The Web Proxy generates a core file when a client application uses HTTP pipelining 
(multiple HTTP requests are written out to a single socket without waiting for the 
corresponding responses) due to internal memory management issues.
