No worries, this is perfect, thank you for the tips.
I'm already wondering about the `mbufs' output from systat(1)
(especially the ALIVE column):
After a reboot + 20 minutes:
1 users Load 0.46 0.38 0.33 firefly.ecentrum.hu 16:40:43
IFACE LIVELOCKS SIZE ALIVE LWM HWM CWM
System 0 256 4100 260
2048 3717 468
2112 53 7
4096 128 20
9216 17 12
After two days:
1 users Load 0.14 0.20 0.22 firefly.ecentrum.hu 15:00:00
IFACE LIVELOCKS SIZE ALIVE LWM HWM CWM
System 0 256 215K 13780
2048 * 26954
2112 66 9
4096 128 25
9216 11 11
How does ALIVE: 215k look after two days uptime with mild internet
traffic? Is this something that could be a potential culprit or am I
just reading things into that?
And I'm just guessing but that star either means infinite :) or that it
couldn't even write the number into that space.
