Issue:
We are using the policy-based installation option to upgrade our clients, from which we receive status "Failed: download interrupted"
Resolution:
By default WithSecure Policy Manager Server can handle a maximum of 50 simultaneous package download requests. If the network cannot handle the bandwidth required for 50 simultaneous downloads, the policy-based installation or upgrade operation might fail. This error can also be the result of, if you have a sub-network with low bandwidth, which tries to fetch packages for several minutes.
For a network with low bandwidth, that can not handle such a high network load, we recommend to use the Policy Manager Proxy as an option.
Policy Manager Proxy offers a solution to bandwidth problems in distributed installations of Client Security and Server Security by significantly reducing load on the networks. More about this topic can be found in the Help Guide. The Policy Manager Proxy can be downloaded from the WithSecure page: WithSecure™ Download Center | WithSecure™
Another solution, which can decrease the network load, is to use the additional_java_args setting: -DmaxSynchronousPackageRetrievalRequests=25
This settings changes the maximum number of simultaneously handled package download requests for policy-based installations.
You can apply this change on your WithSecure Policy Manager Server by following these steps:
- Open the Command Prompt as an administrator and use the following command to stop the Policy Manager Server service:
- Policy Manager 15: net stop fsms
- Policy Manager 16: net stop wspms
- Open regedit and navigate to:
- Policy Manager 15: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Data Fellows\F-Secure\Management Server 5
- Policy Manager 16: HKEY_LOCAL_MACHINE\SOFTWARE\WithSecure\Policy Manager\Policy Manager Server
- Select additional_java_args and double-click it
- Enter the following string to Value Data: -DmaxSynchronousPackageRetrievalRequests=25
- Use Command prompt to restart the Policy Manager Server service:
- Policy Manager 15: net start fsms
- Policy Manager 16: net start wspms
Note: If there is no existing additional_java_args registry entry, you can create one. Set the type as REG_SZ.
