Is there anything special about your environment that mi= ght=20 > especially trigger this issue? Is it a VM or running on the host machin= e etc.? Hi Bruce, I appreciate for your testing. I've tried it on an another system, and I couldn't reproduce it. Could you please see below? - The system I can reproduce the issue OS: Ubuntu14.04 Kernel: Linux eris 3.13.0-30-generic CPU: AMD FX(tm)-8350 Eight-Core Processor NIC: Ethernet controller: Intel Corporation 82572EI Gigabit Ethernet Controller (Copper) (rev 06) - The system I cannot reproduce the issue OS: ubuntu14.04 Kernel: Linux ubuntu-igel 3.13.0-30-generic Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz NIC: Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) I will check it more in next testing phase. Until then, I will use the system I cannot reproduce the issue. Regards, Tetsuya > Regards, > /Bruce >
