Spacelynk Cpu load high - domotiqa - 28.05.2018
Hello,
I have a very high cpu load on customer Spacelynk. The Spacelynk wasn't installed by me, but I think it is very strange ! I tried to do a Factory reset without difference ! Do you have Idea ? I also upgrade to 2.1.1 firmware without any difference !
There is no script.. If I put the backup on my test Spacelynk th load is 0,1%
What is fun, is that when rebooting, it start from 0.5 then it's growing in the 3 min to more than 1

RE: Spacelynk Cpu load high - admin - 28.05.2018
Start with disconnecting client devices and checking KNX/IP bus load.

knx bus load is 10% average. Never above 20% (except when programming with ets).
I disconnect the Touch screen HP slate 21 (android), same cpuload that increase from 0.3 at boot to 1 after 5 minutes.
Ask my self about hardware issue or something else !
I did factory restore from web interface. Should I do something else ?
PS: For info, I know there is 2 knx Ip device on the same network (2 other line as backbone router). I tried to disable Ip stuff from Spacelynk without any difference
RE: Spacelynk Cpu load high - admin - 28.05.2018
Are you sure there are no scripts running at all? Infinite loop in/between scripts or a resident script with sleep time set to 0 can consume whole CPU.
RE: Spacelynk Cpu load high - domotiqa - 29.05.2018
looks like there is multiple send of telegram (with routing number wich increase). For example a telegram from a temperature sensor is send on the bus. But when i log, i see it more than 5 time.
The line 1 is with Schneider Ip router
The line 2 is with Schneider Ip router
The Spacelynk is on line1, but also with IP interface (multicast adress are the same than the 2 Ip router). I will try to put a different multicast Ip adress to test.
RE: Spacelynk Cpu load high - Daniel - 29.05.2018
Hi
It looks to me that you have KNX loop. Disable KNX IP features.
BR
RE: Spacelynk Cpu load high - domotiqa - 29.05.2018
The Ip feature is needed to program Product when away from the customer building (I use script to enable/disable).
Looks like it's working when changing multicast adress. The standar one is 224.0.23.12. So i imagine that the Spacelynk see it on the Tp part, and also on the multicast Ip adress, then maybe try to send it again on Multicast...
I change it on spacelynk:
224.0.23.13
I let the both Ip router on 224.0.23.12.
Now I have telegram send only one on the bus monitor and i know can program with Spacelynk (I couldn't before, timeout error).
The second option I had what to disable Tp feature, and only use Ip with both router.
What do you think about this study case
RE: Spacelynk Cpu load high - Daniel - 29.05.2018
Hi
What for do you have KNX IP router and SL connected to the same line?
Different multicast is another way of solving this design issue
BR
RE: Spacelynk Cpu load high - domotiqa - 29.05.2018
yes, the design is very strange.
They have 2 building and instead of using tp coupler they used 2 Ip router.
What you said is to switch one Ip router and using Spacelynk as router? I thing it's less failsafe to use Linux software instead of Knx tp product to do the job.
RE: Spacelynk Cpu load high - Daniel - 29.05.2018
Yes, but it is your choice.
If you keep both just take this in to account that 2 routers ether must have different multicast or KNX IP disabled otherwise KNX loop is created.
RE: Spacelynk Cpu load high - equalizer - 04.12.2018
Shut down the filter tables in the SL to break the loop. :-)

I disable multicast on SL
