SSL3_GET_RECORD:decryption failed or bad record mac

[Amit Ben Shahar]

I am having issues with a server, i'm getting many of these errors
especially while running a load (~80 users).
here is the full error message:
error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record
mac

It seems to be occurring during the negotiation (accept) phase.
Maybe something is wrong with the cipher options?

Here is my context generation code:

// generate the context with SSL version 2,3, and TLS support

    SSL_CTX* ctx = SSL_CTX_new(SSLv23_method());


>     // Set the context mode

    SSL_CTX_set_mode(ctx,
> SSL_MODE_AUTO_RETRY|SSL_MODE_ENABLE_PARTIAL_WRITE);

    // Set the workaround options

    SSL_CTX_set_options(ctx, SSL_OP_ALL);

    // not verifying client certificate

    SSL_CTX_set_verify(ctx, SSL_VERIFY_NONE, 0);


>     // Set the client certificate max verification depth

    SSL_CTX_set_verify_depth(ctx, 10);

    // Load certificate from file

    int res = SSL_CTX_use_certificate_file(ctx, certificateFile.c_str(),
> SSL_FILETYPE_PEM);

    if (!res)

    {

        unsigned long error;

        char errBuff[1024];

        do

        {

            error = ERR_get_error();

            ERR_error_string_n(error, errBuff, 1024);

        } while (error);

>         throw "Error loading SSL certificate";

    }

    // Load private key from file

    if (!(SSL_CTX_use_PrivateKey_file(ctx, privateKeyFile.c_str(),
> SSL_FILETYPE_PEM)))

    {

        throw "Error loading SSL certificate";

    }

    // Set the session id context

    SSL_CTX_set_session_id_context(ctx, (const unsigned char
> *)sessionIdContext.c_str(), (unsigned int)sessionIdContext.length());


>     mContext = ctx;
