https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=198406 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. -- You are receiving this mail because: You are the assignee for the bug.
