Error description

  • The ebcdic string "CCVT" is leaked each time the method
    
    Java_com_ibm_crypto_hdwrCCA_provider_HIKM_SetupCardInformation
    
    is called inside the z/OS Java hardware cryptography provider (
    IBMJCECCA ).
    
    
    On systems where the IBMJCECCA provider is installed
    the leak may result in native memory problems. When combined
    with the Language Environment malloc header, this leak is 12
    bytes in size. In a HeapPool environment, the leak may manifest
    as large numbers of HeapPool extents for the size containing
    these entries.
    
    KEYWORDS:
    
    ibmjcecca.jar hdwrCCA SetupCardInformation java memory leak
    
    
    
    FIXED IN JAVA 6 UNDER APAR IZ95421
    

Local fix

  • If the 4 byte native memory leak is affecting your system, you
    can revert to the Java software Cryptography Extension provider
    (IBMJCE).
    
    NOTE: This leak does NOT affect Java Heap storage. This is a
    leak within Language Environment heap memory.
    

Problem summary

  • A 4 byte memory leak occurs in the method
    Java_com_ibm_crypto_hdwrCCA_provider_HIKM_SetupCardInformation()
    of the IBMJCECCA provider on z/OS.
    

Problem conclusion

  • This defect will be fixed in:
    5.0.0 SR12 FP4
    .
    The 4 bytes of memory are no longer dynamically allocated. The
    memory leak will no longer occur.
    .
    To obtain the fix:
    Install build 20101204 or later
    

Temporary fix
