https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217606 --- Comment #20 from Fabian Keil <fk@fabiankeil.de> --- Created attachment 186372 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D186372&action= =3Dedit ElectroBSD r323013-16c8587cb1b5 dmesg on HP Proliant TL;DR: I'm attaching a dmesg output as requested but as it looks like the problems are unrelated the system differences are probably irrelevant. I currently don't use ix devices. As mentioned in comment #13 it's not obvious to me that Aiko's issue is uma related and I mainly mentioned the patches as the symptoms look somewhat similar and no other suggestions were made at the time. The fact that the uma patches didn't help on the punkt.de system(s) seems to indicate that it's another issue as well (but maybe the same as Aiko's). On my systems the uma regression resulted in established tcp connections getting terminated after a while. It could take days for the problem to occur so I've mostly noticed it with ssh connections. Terminated connections could be reestablished without restarting any interfaces and the problem didn't affect all connections at the same time either. I've created the if_bridge patches after noticing that ssh connections on a bhyve host to the bhyve vms got terminated a couple of times in a similar fashion. At the time the bhyve host and vms were running ElectroBSD based on FreeBSD stable/11 from March 2017 and already contained the other tcp regression fixes. The bhyve host is a HP DL120 G6 using a bridge1 between tap devices for vms with access to the Internet and bridge0 between tap devices from vms without access to the Internet. pf is being used to nat on bge0 to bridge1. After applying the if_bridge patches the local ssh connections to the bhyve vms stayed up so I haven't looked into this any further. I also didn't verify that removing the if_bridge patches reintroduces the problem again to confirm that there's indeed a causation (and the problem wasn't fixed by syncing with stable/11). --=20 You are receiving this mail because: You are the assignee for the bug.=
