I never ran netstat -mb when I was encountering the network memory allocation error. At the moment I have adjusted net.graph.maxdata from the default value to 8192, rebooted, and have not encountered any more network memory allocation errors (and vmstat -z shows 0 NetGraph data item failures). If, at this maxdata setting, they show up again I'll post the output of netstat -mb. If it's worth anything, current output of netstat -mb is below.
