DragonFly users List (threaded) for 2005-02
em driver - issue #2
Ok, now thats its not crashing anymore, on to the next problem. After
starting the traffic generator, I now get the expected
"All mbuf clusters exhausted, please see tuning(7)"
message. However it apparently locks up the controller, or at least
it doesn't recover as expected. Once I stop the traffic generator,
other interfaces on the dragonfly machine operate normally, but
the one that was being pounded cannot receive. If I initiate a
ping from the dfly box out of the problem controller, then it starts
working ok. I also get a
"Limiting ICMP unreach response from 11768 to 200 pps"
which implies that quite a few packets get "stuck" somewhere and
are all released at once when a transmit is initiated, since
the traffic had stopped arriving long before.
I'll have a chance tomorrow perhaps to dig a bit deeper, but any ideas
about what might have been changed to cause this (as this isnt a
problem in freebsd) would be helpful. I can also try it on an fxp
interface to see if its an em problem or a system-wide problem.
