The unreserved disk space is kept to the limits as content updates are downloaded. Once the limit is reached, the Group Update Provider continues to serve the clients, but only for the existing content.
Maximum number of simultaneous downloads to clients
Configure the Group update provider settings, for' Maximum disk cache size allowed for downloading updates' , and for 'Maximum number of simultaneous downloads to clients' to appropriate values so that clients would get the updates from GUP, and GUP would have enough space to be able to store updates for even the old content request from clients.
To configure these options:
Symantec Endpoint Protection Manager is installed on a Windows 2003 Server, and the Group Update Provider setting is configured in the LiveUpdate settings policy for the clients.
There are clients from the same group and subnet that are updating, however a few are not.
