Strange CPU behaviour ... old & new builds.

[admin]

Just latest 2/3 days two of the openWrt boxes running as repeater (r47603 & r44367) have same Wlan issue, losing connection every 5 minutes sometimes even every 5 seconds! Even after re-established connection the CPU usage is about 85% for a minute or so, then it's back to normal, about 10%.

With 'top' command running on background, nothing is seen active!
Is this only on 'real time' graph or what? As i already switched off almost everything including collectd and luci-statistics etc.
On second console we see renew wlan connection:

[ 8763.380000] wlan0: associated

I did also changed MAC of second box (lib/firmware/RT3062.eeprom), as they both were using the same. Already made sure not to use both boxes in 'ON' mode
Now i can use them both ...

This doesn't look normal to me, if there's no real network traffic.
Looks like issue: https://dev.openwrt.org/ticket/9875

And 'luci-bwc 9' could be with a '4' or a '7'.

Further investigating, as i didn't had this experience last running year, only after new rebuild.
Could be that i'm using the wrong 'RT3062.eeprom' file.

I know that privoxy also uses 'some' CPU, but normally (earlier tests) not more than 10 / 15%.
These strange peaks to 80 or 90% CPU causes even network issues as:
- time outs;
- wlan losses.

I have a F1 running OpenWrt Chaos Calmer r44257 relatively stable, but the wlan connection is more often re-established.
No idea why, as the connection-point is now 10 meters closer as before?
It does this sometimes 5 times a minute, loosing all connections

For testing (again) switched over to the OpenWrt Designated Driver r47603 on F1, but still after 2 hours usage it looks like the box is soo busy with 'something':



Also Collectd has a strange 'figure':



Strange however that i can't find anything with 'top' that uses a lot of CPU %, on my putty session to the same box:

I probably have to make new openWrt image, with a less as possible libraries, as some are now 'automatically' added (like atm-esi) which i don't need -or use- and can be removed without any change (on my configurations) ...

And pitty enough, with this new code (& probably newer Privoxy), my Pokergame wont start, missing internet? (or that's another issue, now...)
That's because DHCP isn't working (anymore) in 4.1.11?

OpenWrt CC r44257, does do the DHCP normally & works fine (also with the poker app).
This is probably due to .dts settings on the r44257 build, i have to check this.
But some other strange things are going around here ...

Default dsl options are enabled, but as i don't have (or need) it, removed all dsl related software from the default build (CC or DD) will fix the busy loads.



Removed from default build:
- ltq-vdsl-mei_test
- ltq-vdsl-app
- kmod-ltq-vdsl-vr9-mei
- kmod-ltq-vdsl-vr9

I left the atm options as-is, these don't interfere with device load.

Although below 1 this looks better, without the dsl options.

The first 2 pictures in this article, where from my old build openWrt (r44367).
And the peaks there of bout 0.80 could be normal as the box does proxy all internet traffic through Privoxy.
On the new 4.1.11 build, r47603 (default) i have some more extreme examples, with a peak of 3.65 with all dsl components active:



Removing all the dsl components result in 'normal' behaviour, assuming the box still proxy all traffic.
As just above, although it's still on the high side with a peak of 0,78 over 15 minutes.

Just 4 the record, the new image build is:



Conclusion:
If you don't need DSL, remove all the components with dsl in the name (System / Software / [search] dsl).
I removed the earlier mentioned router apps.
Most probably these functions will timeout due to no DSL available and mess up with other router jobs (could be Privoxy in my case).
I.e. queing up of router commands. It will be fixed as seen in the graphs, slowly going down level, until the next (i guess) DSL timeout.

Ok for an overview of OpenWrt DD on ZyXEL P-2812HNU-F1.

Default builds with dsl functionality (but no DSL connection) are a No-Go, as the F1 will get too much timeouts!
Even a normal DHCP requests can not be made in time? I'm investigating even the atm functionality, as the F1's i use 4 testing without the dsl functions, still have some strange graphical CPU usage (internal & collectd graphs), which i can't find out what it is.
Even with putty's 'top' command running next to graphs, can't figure it out.

So even without dsl functionality i get strange CPU readings with even value's over 4.0 are mentioned? - 27 jan (2) & 5 feb(2) -
What could cause this?

Here some examples:
Notice that within overview of 1 day, these peaks get lowered? (5 feb (1) r48507)
