https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235524 Mel Pilgrim <ports.maintainer@evilphi.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ports.maintainer@evilphi.co | |m --- Comment #7 from Mel Pilgrim <ports.maintainer@evilphi.com> --- I believe this is still recurring, even on 12.1-R, and that pf is involved somehow. Every few weeks, a server will go offline. When I bring up the management console, the link light is off and the console is full of errors like this: igb1: Watchdog timeout (TX: 2 desc avail: 42 pidx: 504) -- resetting igb1: Watchdog timeout (TX: 2 desc avail: 1024 pidx: 0) -- resetting With the first occurring once, then the second repeating every 2-3 seconds. If I ifconfig down the interface, the watchdog timeout errors cease and the link light comes on. If I then ifconfig up the interface the link light go= es off again and the watchdog timeout errors resume. Thus far, only rebooting fixes this state. Anecdote: this behaviour seems to correlate to whether or not pf is in use.= I have multiple of this exact hardware (Supermicro X11SSH-LN4F), some run pf, some don't. The behaviour occurs on every machine running pf, and none of t= he ones not running pf. It wasn't occurring on two machines for months, then = pf was enabled, and the behaviour started. It was occuring on one of the mach= ines running pf, then pf was disabled, and after months it has not recurred. I'm posting this here because the observation--the paradoxical if up/down behaviour fixed only with a reboot--is the same, and I have machines running 12.x that do it, suggesting this has only been partially masked. --=20 You are receiving this mail because: You are on the CC list for the bug.
