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

• Fix is available in 7.0.0.16, 7.1.0.13, 7.2.0.10, 7.5.0.4,
  7.5.1.3 and 7.5.2.1
