Overloaded Appliances: 
Symptoms and Solutions
Symptoms
Some symptoms of an overloaded or busy appliance include:
•  HTTP time-out errors that occur while submitting configuration updates in Advanced View.
•  A significant delay between the time at which the alert condition occurred and the time at which 
the alert notification was delivered, based on the time of the alert noted in the notification.
•  Audio clips and/or camera clips associated with an alert notification are missing. 
•  Your appliance reboots on its own.
•  In the Camera view, a significantly lower-than-expected frame rate is served by the appliance (this 
is often due to a heavy alert load, and can also be caused by several users attempting to 
interactively view camera images from the same appliance simultaneously).
•  When attempting to load the alerts in the Advanced View Alerts view, you receive an Error 
loading the list of Alerts error message.
•  When attempting to load sensor graphs, you get time-outs.
•  Configuration panels take long times to load, or time-out when attempting to load.
•  Upgrade attempts are unsuccessful with errors indicating that the appliance is too busy.
•  When viewing alert details, you receive errors when attempting to load-up graphs and/or camera 
clips with a message indicating that the graph or clip had to be removed to make room for more 
recent alert captures. Additionally, expected camera or graph attachments for an alert have been 
deleted.
•  In the Web Client, you notice a long delay in information appearing when you navigate the web 
site.
