After upgrade to 6.12.4 - Unraid randomly becomes unresponsive. CPU pegged 100%

Issue still exists.

Would appear, this issue appears to potentially be related to one of my docker containers.

Happened to have a top running, and noticed a certain "java" process using a ton of CPU. stopped the container which uses java on the backend. Will post updates, if this turns out it was the problem.

Nope. went and ate dinner after stopping suspect containers.

Tried to turn plex on TV, and its dead. 

Get back to observe, Unraid is completely unresponsive, using around 16 threads worth of CPU.

No services responding. No NFS, SMB, No docker containers responding. No SSH. Nothing.

 

Rebooted the underlying host. going to keep troubleshooting things on my side...

So far, appears that may have resolved the issue. If the issue doesn't crop up again tomm, will close this one.

Ran a full hardware diagnostics / memory scan. Came back clean.

So, re-updated to 6.12.4.

Moved docker to a dedicated NIC, following the instructions linked from release notes. Changed docker from ipvlan to macvlan. Disabled bridging on NICs.

Has been running stable so far. Will post again this evening.

Since, doing those changes this morning, its been rock solid.

Appears my issue was related to networking, bridges, docker, etc....

Changed Status to Solved

Hi, 

 

Can you provide screenshots on how have you configured the Docker and the Network Settings pages? I'm currently struggling with random freezes and would like to test your setup.

 

Best

Sure- and to note- it has been rock solid since re-configuring the networking.

 

 

 

 

 

Will try it like this, thanks.
