  • Closed as program error.

Error description

  • Executing runmqras against an RDQM queue manager as root may
    cause a kernel crash
    

Local fix

  • Comment out or remove the following line of the isa.xml file in
    the MQ installation:
    
    <command name="MQBIN::/rdqmadm" args="-xd WorkDir::/drbd_debug"
    output="rdqmadm-xd" env="rdqm"/>
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of the RDQM functionality, who execute
    the runmqras diagnostic utility as the root user on a system
    with one or more RDQM queue managers defined.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    An error in the underlying DRBD libraries used by the RDQM
    feature meant that a diagnostic call made during the runmqras
    execution could result in a kernel crash.
    

Problem conclusion

  • This APAR temporarily disables the affected diagnostic call made
    by the runmqras utility.
    
    It will be restored when a fix for the underlying issue within
    the DRBD component is available.
