Deco M4 system logs - repeating entries and lost connection, high CPU usage
Hi all,
Looking for some help please with some error logs. I was drawn to check the logs, following some issues on a device which is losing connection regularly, and causing stuttering video. (Sky Q box). No other devices are suffering noticeable issues.
I have no idea how to interpret these, so help is appreciated. So far I've tried deleting the network and resetting all Decos. They're running most up to date firmware.
To summarise the symptoms:
- the device which is having issues seems to be losing connection regularly enough to affect performance.
- No changes to LEDs are visible on the Deco
- The main deco router has spikes in very high CPU usuage, sometimes up to 100% - so something is causing a strain
- Reviewing the logs, there are multiple entries every minute which is a concern. combination of errors, warnings and information
- IPV6 disabled
- IPTV / VLAN disabled
- UPNP enabled
- IGMP disabled
- WAN unicast disabled
Link to the latest log is here https://www.dropbox.com/s/xgr0y50worzs4kk/log-2021-08-03.log?dl=0
Any help appreciated. Some log excerpts are copied below:
