I'm testing an Ethernet driver on FreeBSD 6.3.
Running netstat -m during an ethernt stress test I see that the
"mbuf+clusters out of packet secondary zone in use" number is growing
gradualy. Problem is it never goes down after I stop the test, so it's
pushing the "mbufs in use" up until the following stress test iterations
reach the OS limit. What does this number mean?
It seems likely that one of two things is happening:
(1) a leak of mbuf + clusters
(2) a bug in stats on mbuf + clusters
Could you paste the output of "vmstat -z | grep -i mbuf" into an e-mail?
That's the underlying vm stats from the zone used to generate netstat -m
output, and might shed more light on things.
