Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This has only been seen by users of WebSphere MQ v7.0.x with
    SUSE Linux Enterprise Server 11 SP1 (x86_64) - Kernel
    2.6.32.29-0.3-default (10) however it might occur with any Unix
    system.
    
    Platforms affected:
    All Unix
    
    ****************************************************************
    PROBLEM SUMMARY:
    WebSphere MQ was relying on a call to localtime_r() to set a
    tzname variable. This is not always set on return from the call.
    

Problem conclusion

  • WebSphere MQ has been modified to ensure that the tzname
    variable returned from localtime_r() is correctly initialized.
