https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D198406 Bryan Venteicher <bryanv@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bryanv@FreeBSD.org --- Comment #8 from Bryan Venteicher <bryanv@FreeBSD.org> --- There is no limit in the vmx(4) driver; it sounds like interrupts are broken when the fifth interface is added. If the driver negotiates multiqueue (only if MSIX is available) perhaps we = are exhausting some MSIX limit but an error is not bubbled up. You could try setting the `hw.vmx.mq_disable` tunable to disable multiqueue. Unfortunately, I don't have access to an VMware ESXi environment to do any investigation. --=20 You are receiving this mail because: You are the assignee for the bug.=
