Hi everyone,
I still haven't upgraded to 4.7 yet (I will do soon), so I'm still on 4.6.
On my home server, I run symon and syweb to monitor several stats about my
machine. I noticed that since about 3-4 months ago, the mbuf usage started
to to increase and never decrease. The mbuf type responsible for this is
mt_soname. The other thing is that this machine just sometimes reboots, out
of nowhere. This may or not be connected to the mbufs.
This sudden increase in mt_soname mbuf coincides with my replacing an
external ADSL modem with an internal one (a Traverse PCI card, appearing as
an RTL8139C+ to the system). The type of DSL connection changed as well, I
now use dhclient to get an IP address.
Can I investigate where these mbufs are used? As I said, I'll upgrade to
4.7 soon, so I primarily see this as a learning opportunity for me.
Thanks,
