    * PROBLEM DESCRIPTION:                                         *
    * When running the CLI "mfp push" command increases the amount *
    * of memory the process is using and the number of loaded      *
    * classes leading to potential performance issue.              *

Problem conclusion

  • Limitation : due to the Liberty Profile classloader's mechanism
    it is not possible to fix by configuration this issue. Changing
    the classloader configuration of a MobileFirst runtime
    application definition can lead to serious dysfunctions.
    
    To avoid the performance issue when you run n times the mfp push
    command you need to set the JVM heap size of the Liberty server
    minimally to n x 45 MB.
