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

    • Solved Minor

    I upgraded to 6.12.4 earlier this week, after upgrading, I went from a perfectly stable, and reliable system, to one that now... just breaks randomly. 

    The symptoms I notice, include maxed out CPU. I am unable to ssh, or even use the root console while this is occuring.



    Disabled a few things, doubled the allocated resources. 

    No VMs, only docker, storage, nfs, and smb.

    Going to downgrade to 6.12.3. Diagnostics are attached.

    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.

    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.

    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.
