• [6.9 Beta 22]-> [6.9 Beta 25] BUG: unable to handle page fault for address


    mf808
    • Closed Minor

    I had my unraid server crash on me.

     

    Web Front End is not anymore responsive.

    SSH Login with root does not work.

    Docker Containers are working.

     

    Running 6.9 Beta 22

     

    From my syslog server I was able to pull this information.

     

    I assume the server was running for about 20 days.

    Hi Squid,

    thanks for your reply.

     

    I added the diagnostic file. Although it was created after a reboot.

     

    How much more of the syslog is required? The excerpt I have copied above is the first occurence of this error. After that it keeps repeating.

    Upgraded to beta25

     

    System ran for again around ~22 days then became unresponsive.

    I do have a syslog, which I copied into the diag zip.

     

    Does this look like a memory issue? 

    First error appeared:

    And then this error then keeps on repeating until the machine halted
    The timestamp coincides with a sonarr docker container processing a downloaded (nzbget docker) or just right after.
    So there was activity.

    Good call. Turns out I had a bad stick.

    Removed the bad kit and did a 16 hour run of Memtest86 without errors. 

     

    I will retest. 

    Link to comment

    After 27 days with the new kit of ram it hasnt crashed or shown any errors yet.

    I call this closed.
