Dear All, I am stuck with a machine that shows serious packet loss (about 1% of = all traffic is dropped). 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/ kjkoster@kjkoster.org +31651838192 Change is good. Granted, it is good in retrospect, but change is good.
