Continuous Discovery Rapidly Consumes Memory

Symptom:

Continuous Discovery consumes a lot of memory and creates incorrect subnets.

Solution:

Continuous Discovery retrieves the local subnet from the agent computer. If the agent is running on a computer with an incorrect subnet configuration, Continuous Discovery calculates the IP addresses of subnets and devices incorrectly, which results in incorrect data in the Continuous Discovery agent, causing it to rapidly consume memory.

Verify that the subnet mask is set correctly. The default subnet mask that Classic Discovery uses is 255.255.255.0. If the subnet mask is different, specify the -N subnet-mask parameter in the dscvrbe command, or set the subnet mask on the Discovery Wizard or Advanced Discovery Subnets Page in Unicenter MCC. Classic Discovery also retrieves subnet masks from a router if SNMP is enabled. Be sure that subnet masks are set correctly for all router interface cards that were discovered.
