Long term memory leak when using PKCS11 and JCE exceeds 32 bit process address space

    XMLWordPrintable

    Backports

      Description

        Both recent JDK1.6 and JDK1.7 (build 76 last tested) runs of a simple NIO Server using JCE cryptography results in the server running out of memory after a few days of running. The customer's real application runs out of memory after a few hours.

        The exact same code running with sunpkcs11 provider line commented out of the java.security file quickly reaches a steady process address space limit and remains there indefinitely, so the leak is definitely in our pkcs11 layer that apparently is needed to take advantage of CMT cryptographic acceleration. This has been replicated on T5120 S10u7 and T2000 S10u6 machines, and I've attached a tarfile.
