Local fix

Problem summary

  • Under low memory conditions, heap allocations in the shutdown
    code could trigger an OutOfMemoryError.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR3
    6.0.1 SR4
    6.0.0 SR12
    .
    The Attach API code has been modified to avoid memory
    allocations during shutdown and suppress irrelevant
    OutOfMemoryErrors.
