Subject: [dpdk-dev] L2FWD Sample Application stops receiving packets after sometime
Date: Thu, 20 Mar 2014 09:11:42 +0000 [thread overview]
Message-ID: <2AA69572D8087D4FA7345FB70631D59A1FD71474@SGSIMBX007.nsn-intra.net> (raw)
Hi,
I am currently running few trials with DPDK sample application for one of my project requirements. Below are the system details under which the sample application (L2 Forward) is being run.
Platform: Linux 2.6.32-358.17.1.el6.x86_64
VMWare: ESXI 5.1
Driver: vmxnet3-usermap
L2 FWD program is being run with a load of ~100K packets per second on RX queue. The sample application successfully forwards the packets to other end for some time. However, after around 1 hour run, I see that rte_eth_rx_burst returns 0 packets received, though the load generator continuously sends packet to the L2 FWD program.
The statistics reported by the sample application also shows the "Packets received:" value stops incrementing.
I also used "rte_eth_stats_get" api to check if any packets are being received on the interface. This api shows the packets are being received at the interface, however rte_eth_rx_burst does not pick these packets.
Can you please help me as to why this behavior is seen. Also, please let me know if you need further details. Thanks
~Neeraj
