While testing the RIC platform it is observed that - sometimes the e2term pod does not reach the *Ready* state. This condition is observed intermittently but often enough (say about 40% of the times).

The condition is observed on `minikube` on `Ubunutu 22.04`. Not sure whether this is related to the platform per se.

Observe that the Pod is not up after more than 15 mins.

$ kubectl get pods  -n ricplt

Below are some of the logs and initial analysis of the condition.

The container is started with verbose log level, it can be observed that the DEBUG logs are indeed printed initially but later on only INFO logs are printed. Which suggests some or heap corruption.

Most likely this is related to the following function

void sendTermInit(sctp_params_t &sctpParams) {
    rmr_mbuf_t *msg = rmr_alloc_msg(sctpParams.rmrCtx, sctpParams.ka_message_length);
    auto count = 0;
    while (true) {
        msg->mtype = E2_TERM_INIT;
        msg->state = 0;
        rmr_bytes2payload(msg, (unsigned char *)sctpParams.ka_message, sctpParams.ka_message_length);
        static unsigned char tx[32];
        auto txLen = snprintf((char *) tx, sizeof tx, "%15ld", transactionCounter++);
        rmr_bytes2xact(msg, tx, txLen);
        msg = rmr_send_msg(sctpParams.rmrCtx, msg);
        if (msg == nullptr) {
            msg = rmr_alloc_msg(sctpParams.rmrCtx, sctpParams.ka_message_length);
        } else if (msg->state == 0) {
            rmr_free_msg(msg);
            if (mdclog_level_get() >=  MDCLOG_INFO) {
                mdclog_write(MDCLOG_INFO, "E2_TERM_INIT successfully sent ");
            }
            return;
        } else {
            if (count % 100 == 0) {
                mdclog_write(MDCLOG_ERR, "Error sending E2_TERM_INIT cause : %s ", translateRmrErrorMessages(msg->state).c_str());
            }
            sleep(1);
        }
        count++;
    }
}

Here rmr_send_msg is called inside a while(true) loop, but this function get's called from the handleTermInit function in another while loop. Possibly causing some issue in the rmr?

Instead if the code in the sendTermInit - instead of sending the message in a while loop only sends it once, this issue is not observed.

Modified sendTermInit looks like. (Note: while(true) loop is no longer present.)

void sendTermInit(sctp_params_t &sctpParams) {
    rmr_mbuf_t *msg = rmr_alloc_msg(sctpParams.rmrCtx, sctpParams.ka_message_length);
    msg->mtype = E2_TERM_INIT;
    msg->state = 0;
    rmr_bytes2payload(msg, (unsigned char *)sctpParams.ka_message, sctpParams.ka_message_length);
    static unsigned char tx[32] {};
    mdclog_write(MDCLOG_INFO, "sizeof tx: %d", sizeof tx);
    auto txLen = snprintf((char *) tx, sizeof tx, "%15ld", transactionCounter++);
    rmr_bytes2xact(msg, tx, txLen);
    msg = rmr_send_msg(sctpParams.rmrCtx, msg);
    if (msg == nullptr) {
        msg = rmr_alloc_msg(sctpParams.rmrCtx, sctpParams.ka_message_length);
    } else if (msg->state == 0) {
        if (mdclog_level_get() >=  MDCLOG_INFO) {
            mdclog_write(MDCLOG_INFO, "E2_TERM_INIT successfully sent ");
        }
    } else {
        mdclog_write(MDCLOG_ERR, "Error sending E2_TERM_INIT cause : %s ", translateRmrErrorMessages(msg->state).c_str());
    }
    rmr_free_msg(msg);
}
