Clients running Inventory Solution for Windows do not appear to have any inventory reported when checking under Resource Manager or running reports from the NS console. The only inventory information shown is the basic inventory.
PostFile to 'HTTP://<NSServerName>/ALTIRIS/NS/Agent/PostEvent.asp' failed: HTTP error: 503 Service overloaded (-2147213300)
NS Event Queue (EvtQFast) is full—returning BUSY
The inventory was unable to be posted to the NS as the event queues were full, preventing the processing of any events and often leading to the hanging of the Altiris Client Message Dispatcher service. IIS error 503 indicates that the server is too busy to handle any new requests.
The following was used to resolve the performance issues:
Notification Server 6.0 SP2 Hotfix19
This could apply to any particular Altiris environmental variables. The NS was hosted on a dual processor system also hosting the SQL server.
