[dpdk-users] Running a second DPDK process that prints the NIC's link status/speed causes the first DPDK process to stop transmitting.

I have a small utility application that lists the DPDK interfaces and
prints their link status and link speed. Running this utility while another
DPDK application is running causes that application to enter a seemingly
corrupt state (all transmissions start failing). Apparently the call to
rte_eal_init in the second app is sufficient to break the first app.

Is there a way to avoid this problem?
