I have to agree it's an ugly deal when iperf gives good results. Puts it's validity as a good performance measurement tool into perspective. Another pointer might have been the error counters in ifconfig for that interface. The real paranoid person might consider one's monitoring tool to observe things like that and notify the sysadmins, but I guess you end up spending more time in configuring the monitoring tool than fixing real issues.
