In the server logs, the following warnings appeared frequently:
Process: w3wp (1296) Thread ID: 74 Module: w3wp.exe Source: Altiris.NS.ItemManagement.Item.HandleItemCacheFlooded Description: ItemCacheSize core setting is too small to satisfy the level of cachable item load requests received. Current Size: 3000
Process: w3wp (9272) Thread ID: 102 Module: w3wp.exe Source: Altiris.NS.AgentManagement.PolicyCache.HandleFlooded Description: Core setting ClientPolicyCacheSize is too small to satisfy incoming requests. Current value: 2000
Still under investigation.
It appears that the cache size warnings were indicative, though it is unclear whether the cache flooding is the root cause.
In several customers' environment, increasing the cache sizes referred to by the warnings, until the warnings were eliminated, also eliminated the 'malformed http response' issue during agent client policy updates.
To do this:
1) Open ..Program Files\Altiris\Notification Server\Bin\Tools\NSConfigurator.exe 2) Increase the ItemCacheSize and ClientPolicyCacheMaxSize - Start by doubling the default size. ...By default, the cache sizes are set to 3000 and 2000, respectively. 3) Restart IIS after each increase 4) Monitor the log viewer on the NS - does the warning message re-appear? ....If the warning reappears, repeat steps 1-4.
Note:: . Initially you may want to double the default ItemCacheSize and then monitor the situation after the change has taken affect. If necessary keep increasing the cache sizes in smaller increments until you no longer see the ItemCacheSize warnings
