Local fix

  • N/A
    

Problem summary

  • The problem is caused due to ORB's internal structure holding
    the classloaders from getting GCed in time, which in turn do not
    free up the native representation of the classes in time,
    resulting in native OOMs.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.1 SR3
    .
    ORB code has been fixed to release the classloaders.
