Hey all, I just set up a 4.9based router for my home office last
week and I noticed this morning that it was slow. So I logged
in and threw up a top session and saw this:
PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU
COMMAND
88 root 53 0 33988K 33792K RUN 427:02 94.43% 94.43%
natd
I then did this:
gate# tcpdump -i rl1 -n not tcp port 22
tcpdump: listening on rl1
And saw almost zero traffic. I rebooted thinking natd may have
run away with itself for some reason and upon reboot it came up
with top taking about 16% CPU. After a whopping 2 minutes or so
natd is now taking 65-95% of the cpu time again.
This box is an AMD 350MHz with 256MB of old SDRAM. Not a
bragload of power but it should be overkill for splitting out
routing and nat services for 1-4 workstations surfing the web.
This behavior was *not* present until this morning and I have
added nothing.
Thnx for any insight or troublshooting tips you have, I already
googled and came up craps.
