Hi, Alfredo I did try some earlier version, like 7.5.0 but the management port of my host was killed if I enable RSS. So I have to upgrade to 7.6.0, maybe you will remember that case.
After some work on this, I have found a fast way to reproduce this issue. I wrote a test program and ran it on my host. If I run this program before packets are injected into this host, everything works fine. but if I inject the packets first, the machine will reboot after I start this test program, immediately. And here is the information in /proc/net/pf_ring/info: PF_RING Version : 7.6.0 (7.6.0-stable:0e07b27c0d593174584de79e273470366a91d307) Total rings : 0 Standard (non ZC) Options Ring slots : 65536 Slot version : 17 Capture TX : Yes [RX+TX] IP Defragment : No Socket Mode : Standard Cluster Fragment Queue : 0 Cluster Fragment Discard : 0 The source code of my test is attached, and it can be compiled with: gcc -o test main.c -lpthread -lpcap Thank you for any help.
