Hi

My logs are full of these messages :

I can't find the source of the problem.

Can someone help me please ?

Diagnostics are attached

Stop all docker containers then start enabling one by one to see if you can find the culprit.

Thanks

I had read this thread on the forum before your reply. I disabled all my dockers without really finding the culprit. I then reactivated everything and since then, no more messages in the logs!

The messages reappeared. I will continue to investigate

I'm having the same issue, have you tracked it down?

Check the advanced view on the docker page and look at container uptime, that's typically a container that keeps crashing/restarting due to bad config or such.

I have the same issue.

I added "Homer" as docker container from the CAS. Using "bridge" as network for the docker does not start the container and gives me:

Feb  6 16:49:53 SERVER kernel: docker0: port 5(veth9adb836) entered blocking state
Feb  6 16:49:53 SERVER kernel: docker0: port 5(veth9adb836) entered disabled state
Feb  6 16:49:53 SERVER kernel: device veth9adb836 entered promiscuous mode
Feb  6 16:49:53 SERVER kernel: docker0: port 5(veth9adb836) entered blocking state
Feb  6 16:49:53 SERVER kernel: docker0: port 5(veth9adb836) entered forwarding state
Feb  6 16:49:53 SERVER kernel: docker0: port 5(veth9adb836) entered disabled state
Feb  6 16:49:53 SERVER kernel: docker0: port 5(veth9adb836) entered disabled state
Feb  6 16:49:53 SERVER kernel: device veth9adb836 left promiscuous mode
Feb  6 16:49:53 SERVER kernel: docker0: port 5(veth9adb836) entered disabled state

 

When I give the container an IPv4 address from my custom network on interface br0 it starts up without errors.

 

So I guess its somehow related with the bridging.

 

Edit:

Maybe I may add: This is the only container that does not start using bridge as interface. I have several other containers running well with bridge.

 

Edit 2:

OK I guess I found it. For me it was port related. I had another docker container using port 8080. Unraid did not warn me that the port is already in use (I thought it did in the past, maybe a bug??). But I used another port and now the container starts.

Hi

Back from holiday

All my dockers are up more than 2 days so no problems about accidental restart.

A port of unifi-controller was using 8080. I changed it to 8082. I watch the logs now

No more logs for today, I think I can say it's solved

Thanks

I'm having the same issue and Unifi is using 8080 on mine as well. Can you tell me why it using 8080 is bad? Like why did you even think that was the problem? 😄

Obviously you fixed it, I'm just curious why in the world that made a difference! 😄 

Thanks!

Because 8080 was used by another docker service

Ah okay. Makes sense. I thought this was some sort of fix for anyone with Unifi. 😄

I've read several threads on this and seen several comments that these lines in the log are normal. Guess I'll just let it be. 🙂

Thanks!
