Common troubleshooting steps

When you find an unexpected system reboot or intermittent connection interrupt, the system may encounter a daemon or kernel crash. At this time the most important thing is to collect core/coredump files and system logs, then provide them to R&D for further analysis immediately.

Common checking & analyzing steps:

  • Check if daemon or kernel coredump files are generated

  • Check the basic coredump information

  • Download core & coredump files

  • Collect & download system logs (Listed in Customizing&downloading debug logs, including dmesg & other debugs logs)

  • Possible temporary workaround/solution:

    • Restore the latest configuration or remove newly-added configuration

    • Move away newly migrated traffic if there is

  • Submit bugs and provide information collected for further analysis
