Subscribe

APAR status

  • Closed as program error.

Error description

  • In configurations using many SQL data sources, DataPower might
    spontaneously restart, generating a watchdog backtrace.
    This might be triggered by traffic or by accessing specific
    status providers, one of them being SystemUsage2Table.
    e.g.
    - WebGUI: Status / System / System Usage
    - CLI: show load
    - XML Management: SystemUsage2Table
    - SNMP: dpStatusSystemUsage2TableTable
    

Local fix

  • Avoid access specific status provider,
    e.g.
    - WebGUI: Status / System / System Usage
    - CLI: show load
    - XML Management: SystemUsage2Table
    - SNMP: dpStatusSystemUsage2TableTable
    

Problem summary

  • DataPower might unexpectedly hang and restart when services
    using SFTP, NFS or database connectivity are under heavy load.
    

Problem conclusion

Temporary fix
