For details see #209680. You could check the vmstat -z output and try the patch: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209680#c2 which reverts some of the problematic commits (only in the tcp code, though). Apparently some of the other uma-consumers are affected as well: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209680#c10 and I'm wondering if if_bridge is one of them. You could try if it makes a difference if you let if_bridge set the UMA_ZONE_NOFREE flag and preallocate a couple of items. >From your report it isn't obvious to me that your problem is uma-related so if you have other leads you may want to investigate them first. --=20 You are receiving this mail because: You are the assignee for the bug.=
