            Bug ID: 106
           Summary: running dpdk-procinfo or any secondary leading to
                    system memory exhaustion
           Product: DPDK
           Version: 18.05
          Hardware: x86
                OS: Linux
            Status: CONFIRMED
          Severity: critical
          Priority: Normal
         Component: core
          Assignee: dev@dpdk.org
          Reporter: vipin.varghese@intel.com
  Target Milestone: ---

Issue: Running dpdk secondary instance in multiple iterations leads to memory
exhaustion

Environment: Host & Virtual Machine

Primary App: DPDK l2fwd 

Secondary App: simplified custom app

File:

Secondary:
int
main(int argc, char **argv)
{
        int ret;
        int i;
        char c_flag[] = "-c1";
        char n_flag[] = "-n4";
        char mp_flag[] = "--proc-type=secondary";
        char *argp[argc + 3];
        uint16_t nb_ports;

        argp[0] = argv[0];
        argp[1] = c_flag;
        argp[2] = n_flag;
        argp[3] = mp_flag;

        for (i = 1; i < argc; i++)
                argp[i + 3] = argv[i];

        argc += 3;

        ret = rte_eal_init(argc, argp);
        if (ret < 0) {
                ret = rte_eal_cleanup();
                if (ret)
                        printf("Error from rte_eal_cleanup(), %d\n", ret);

                rte_panic("Cannot init EAL\n");
  }

        ret = rte_eal_cleanup();
        if (ret)
                printf("Error from rte_eal_cleanup(), %d\n", ret);

        fflush(stdout);
        fflush(stderr);
        return 0;
}

Run script:
#!/bin/sh

./build/app/test
ret=$?

while [ $ret -eq 0 ]
do
   sync; echo 3 > /proc/sys/vm/drop_caches
   ./build/app/test
   ret=$?
   echo "ret ---------------- $ret"
done
