My Network Card is continuse go down…..

high CPU is a symptom of the link cycling, the root cause is the link cycling. Figure out why you're cycling link, what are you plugged into, is there a cabling issue, NIC issue, something else going on there.

I had a similar issue with some on-board fxp interfaces. I found manually setting them for 100/full-duplex made them stable. It's worth a shot.

ok , i will try it later..

but now , i turn off webConfigurator Protocol (https) , to use http at pfsense…
then the cpu loading is down....then the NIC is not going down anymore.....

why ?

cmb

It's the opposite, the NIC isn't flapping, so the CPU usage goes down. It has nothing to do with whether you're using HTTP or HTTPS, that's a trivial difference in CPU.

I really don't know.. but why the process```
and [check_reload_status] is continuse high loading....

soory .. cmb

what resion would cause the NIC flapping ?

check_reload_status and PHP have to do many things when link status changes. When it changes non-stop they have to do a lot of things non-stop, using a lot of CPU in the process.

thanks a lot for cmb
I will try to find out the cycling link

This is a driver issue.
Merge all posts from last 2 weeks and you will clearly see that:
a) Cables are OK
b) NICs are OK
c) Switches are OK
d) On some installs like mine there was no change other than pfsense snapshot update…

Greg

Thanks a lot fot Greg ….

last few days , I check the cables , NIC , Switches . It is really found nothing wrong . And the problem would happen at when I upgrape the kernel.
So , I think , It is driver issue , really !
Thanks~

I had the same problem off and on over this past week. I checked everything I could think of then I called my ISP, we ran a series of test and determined it was a bad NIC. I replaced the NIC and haven't had any problems since. Sometimes it's just a simple hardware problem.

Yes, but this is different case…
There are a lot of reports lately about FXP NICs and not all of them have bad hardware...
For bad HW I don`t need to call ISP, I can determine that by myself...
