Well, 1% is not good but I've seen worse for sure! Sounds like you tried the obvious. I would recommend a different IP to rule out a dupe ip; else it must be NIC related - either hardware or driver. Also, perhaps swap cables and ports with a working machine and see if the problem follows or stays put.

I tried the obvious (new network cable, different switch port, different ethernet interface on the machine), but the problems remain. Another machine that sits in the same rack and is hooked up to the same switch shows no such packet loss issues. The problematic machine is a dual Opteron with FreeBSD 8.2-STABLE from Thu Aug 11 14:05:47 CEST 2011. The machine is lightly loaded. A MySQL slave is running, but the machine is not serving queries. Plus a Munin server process. I am at a loss where to start diagnosing this. Can you advise me where to look? Are there network buffers that may be overflowing? -- Kees Jan http://java-monitor.com/ kjkos...@kjkoster.org +31651838192 Change is good. Granted, it is good in retrospect, but change is good. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" <font size="1"> <div style='border:none;border-bottom:double windowtext 2.25pt;padding:0in 0in 1.0pt 0in'> </div> "This email is intended to be reviewed by only the intended recipient and may contain information that is privileged and/or confidential.
