Error description

  • Environment: Solaris
    Problem Description: The ITM Monitoring Agent for UNIX OS hangs
    with two kuxagent processes when collecting network interface
    metrics and in particular the MAC address on Solaris.
    Detailed Recreation Procedure: It is difficult to reproduce this
    concurrency problem.  Try by running queries or situation on the
    attribute group.
    
    
    Related Files and Output: One of the two kuxagent processes has
    a stack
    trace analogous to the following one.  In particular, the stack
    trace
    contains a call to the runCommand function and the parseIfConfig
    function.

Problem conclusion

  • Retrieve the MAC Address programmatically instead of by
    launching an OS command
