Hi all,
Recently, I met a problem of pfring. When the server is connected to
certain traffic, there was something wrong in kernel module and the server
crashed immediately. The traffic is 10Gb/s, which consists of many layers
of VLAN, even more than 10 layers; what’s more, some packet size are more
than 1500 bytes.
Here is the core dump message in /var/crash.

OS information:
CentOS Linux release 7.2.1511 (Core)
3.10.0-327.13.1.el7.x86_64
PF_RING install rpm package:
dkms-2.3-5.20170523git8c3065c.el7.noarch.rpm
pfring-dkms-7.0.0-1541.noarch.rpm
pfring-7.0.0-1541.x86_64.rpm
I want to know whether it is caused by the large volume of traffic or
anything else?
Any insight would be helpful.
