Why does the Package Server log show the error, "Download package sources failed: The maximum number of package info requests has been reached (-2147213300)"?
Altiris.NS.Exceptions.NSComException (Altiris.NS.StandardItems): The maximum number of package server policy requests has been reached. Tune the core setting "MaxPkgSvrConfigRequests" for optimal performance. Current maximum is 2.
There are two action items needed to resolve this.
There is a setting in coresettings.config which allows you to throttle the amount of Package Servers which may request a package info request. This setting is "MaxPkgSvrConfigRequest". This setting needs to be adjusted. Currently there is a hard coded maximum of 3 so there is no need to set it any higher than 3.
You can find out the number of Package Servers you have:
6.0=Configuration tab > Server Settings > Notification Server Infrastructure > Package Servers.
7.x and 7.5 = Settings tab > Notification Server > Site Server Settings, open Site Management then Site Servers
You will need to do some testing in your environment as to the appropriate values.
To change this setting, use the Altiris NS Configurator. If it's not installed, run the following:
