Greetings y=E2=80=99all, We have a massive server with two IXL NICs (Ethernet Controller X710 for = 10GBASE-T). One of them is on the host and the other is passed to a = guest running in a bhyve VM. Every once in a while, the system hangs. We cannot SSH, we cannot ping = nor we can login using console (IPMI remote screen). However, on the console, I see the following messages: "ixl0: ixl_process_adminq: Unable to allocate memory for Admin Queue = event!=E2=80=9D And it keeps repeating. The only way to get access to the host is to=E2=80=A6 reboot it. We don=E2=80=99t use SR-IOV (although when we did, the same thing = happened), we don=E2=80=99t use large MTUs (1500) nor we have a memory = issue (the system has 2TB of RAM, and right before hanging around 250G = is available). Any tip would be appreciated. P.S. we also tried the kmod from ports, still seeing the same issue. Kind regards, =E2=80=94 Antranig Vartanian https://antranigv.am/ PGP Key ID: 0x2D59F21C
