    Background

    Section titled “Background”

    This alarm triggers when we are running out of RAM. The watermark is currently set to 5% of the total (7.8 gb) so around 380 mb.

    Not having sufficient available memory could lead to catastrophic software crashes resulting in paralands. This alarm being set implies that something slipped through validation.

    Troubleshooting Steps

    Section titled “Troubleshooting Steps”
    1 escalation
    All vehicles on this software version should be grounded and should be escalated to P2 Embedded Linux On Call.
