What are Safety Valve Events?
Any CAPM environment
Safety Valve events happen because the network device can't keep up with SNMP traffic. The correct thing to do is definitely to poll either less items on the device or poll less often. So either filter items on the device or poll the device less often - for example every 10 minutes as opposed to every 5 minutes
