How to fix Falcon SIEM Connector high memory usage

Practical checks for Falcon SIEM Connector high memory usage. Follow your organization’s security and change-management policies.

Symptoms and initial checks

Problems related to Falcon SIEM Connector high memory usage can arise from device prerequisites, network settings, permissions, product configuration, or account policy. The exact cause depends on the environment and any displayed error message.

Step-by-step troubleshooting

1. Confirm the scope. Record the affected product, operating system, sensor or console version, and when the problem began.
2. Capture the exact message. Note the full error code, timestamp, device identifier, and whether the issue affects one host or multiple hosts.
3. Check the likely causes. Measure memory usage over time and compare with baseline devices. Check sensor version, system workload, and known compatibility notes. Escalate persistent resource growth with logs.
4. Compare a working system. Check relevant policies, host groups, network routes, and software versions against an approved healthy device.
5. Collect evidence safely. Preserve relevant logs and event details. Remove secrets, personal data, and access tokens before sharing diagnostics.
6. Escalate when necessary. If the issue persists, contact the authorized security administrator or vendor support with the recorded evidence.

What should you avoid?

Do not disable endpoint security, bypass tamper protection, change detection exclusions broadly, or share API keys to resolve an error. For active threats, follow your incident-response process.
