Support Bulletin: ZoneAlarm Slows Server Excessively
Product Version: 3.0.0
Reported OS: Windows
Description:
A customer support ticket indicated Polarion ALM server was taking a very long time to start (over 3,800 seconds), and ran very slow afterwards. The cause was discovered to be the ZoneAlarm firewall. When the firewall was disabled by the customer, the problem persisted. However, When Polarion was installed on a computer with similar configuration but without ZoneAlarm firewall installed, startup and performance was normal.
Recommendations:
For the time being we recommend that you not attempt to run Polarion server on Windows computers having ZoneAlarm installed. We have not seen any problems with Polarion server running on Windows with the Windows firewall installed and activated, so we can suggest that as a firewall alternative.
