Scenario Conditions
CentOS 9 Stream. ActiveMQ 6.1 host NIC showing CRC and frame errors. Packet loss at 5%. Connections intermittently dropping.
Injected Error Messages (1)
ActiveMQ 6.1 on CentOS 9 Stream — nic error detected, crc error rate increasing, network interface errors causing 5% packet loss, activemq connections intermittently dropping, frame error on eth0
Neural Engine Root Cause Analysis
Network interface errors detected — the NIC is experiencing CRC errors, frame errors, packet drops, or ring buffer overflows. These typically indicate physical layer issues (bad cable, failing NIC, duplex mismatch) or driver/firmware problems that are degrading network throughput and reliability.
Remediation Plan
1. Check interface error counters with 'ethtool -S <interface>' or 'ip -s link show'.
2. Inspect the physical cable connection and replace if CRC/frame errors are present.
3. Verify speed/duplex settings match on both ends — auto-negotiation failures cause many NIC errors.
4. Update NIC drivers and firmware to the latest stable version.
5. For ring buffer overflows, increase the ring buffer size with 'ethtool -G <interface> rx <size>'.
Improvements Applied
- Severity: MEDIUM (expected HIGH)
