Error description

  • IBM Spectrum Protect Plus memory and disk usage can increase,
    causing Jobs to fail or restart frequently.
    
    
    This happens when the RabbitMQ component in IBM Spectrum
    Protect Plus is being overloaded and becomes unresponsive.
    
    
    In this specific case, the issue with RabbitMQ is caused by too
    many log files being generated in the background.
    
    
    Review virgo logs at /opt/virgo/servicability/logs and look for
    repeating entries of the quartz scheduler.

Problem conclusion

  • Repeated log statements have been removed from scheduler code,
    which reduces the volume of log messages printed when a job is
    scheduled. This in turn reduces the volume of logging messages
    sent to both the Virgo log and sent through RabbitMQ during job
    scheduling.
