Dear List
Since month I'm fighting against the problem of a lost ethernet link
under load. Searching the net yields that many people using FreeBSD or a
derivate do see that problem, some of them report loading linux on their
hardware makes the problem disappear. There is an assumption of a bug in
the re driver, but no FreeBSD bug report exists.
I would like to know whether you experience similar problems with your
Realtek 8111 variant (or maybe another Realtek chip using the re
driver). To test, send a lot of data through your Realtek-based device
or just to your device, e.g. like this:
- login to your_device and start:
nc -l 10000 > /dev/null
- send data from another machine:
dd if=/dev/zero | nc your_device 10000
After a minute or so, the ethernet link gets lost. Some reporters say
until a manual intervention occurs, in many other cases like mine for a
couple of seconds.
It seems this behavior is quite old and still not solved in newer
versions of FreeBSD (9.1). I hope with the help of this list to find out
it is really an re driver bug and maybe to narrow it down somewhat
closer to help solving the problem and file a bug upstream (if that is
the way it has do be done - or is it common sense to file a bug for
pfsense and let the pfsense devs report upstream?).
Thank you for your help.
Best regards, Adrian.
