(In reply to Ozkan KIRIK from comment #0) We have trouble reproducing this bug in our environment. Could you please provide information specified below? 1. What type of traffic is predominant (UDP/TCP)? 2. Is the same amount of traffic going out and back in or is it only outgoing traffic? 3. What is your port configuration (dump from ifconfig will be helpful)? Hello,
Type of traffic is mixed both tcp and udp. Traffic is generated using WARP17 (github.com/Juniper/warp17) tool. Configuration is req size 1000byte and response size 65535byte both UDP and TCP traffic.

Problem is disappeared in FreeBSD 12.0-STABLE r345762M For future googles, updating to 12.0-RELEASE-p12 fixed this for me. ^Triage: Correct resolution |
I'm using FreeBSD 12.0-STABLE #1 r344160M: Fri Feb 15 After a fresh boot, ix0 works but after a traffic flood (~10Gbps, 1.5Millon pps) ix0 losts link and console fills with "ix0: TX(7) desc avail = 2048, pidx = 0" message. ifconfig down/up doesnt help. System configured as router. Both pf and ipfw is enabled. ring_state of txq flaps between IDLE and STALLED too quickly as shown below: # sysctl dev.ix.0 | grep ring dev.ix.0.iflib.txq7.ring_state: pidx_head: 1644 pidx_tail: 1644
