Cannot start AOS / Error: Cannot create another system semaphore.

Posted on by 2

I had a operating test system of AX 2012 R3 CU8. I used the AX setup tool to uninstall the AOS and then re-install it. Now when I try to start the AOS I get a message that leads me to the event logs where the error reports: Cannot create another system semaphore.

    Fixed it with this:

     

    update SQLSystemVariables

    set value = '4'
    where parm = 'SYSTIMEZONESVERSION'

     

    THIS WORKED FOR ME.

    following are two possible reasons, 2nd worked for me

    -- Add the below permission to AOS SQL user

    • db_ddladmin

    • db_datareader

    • db_datawriter

    -- Update the below query

    update SQLSystemVariables

    set value = '4'

    where parm = 'SYSTIMEZONESVERSION'

    Hi George Hogge,

    Were you able to get a solution for this? Could you please share here as I am facing the similar issue on one of my environments.

    Thanks in advance,

    SKP

    Thanks. None of those options worked for me, but I appreciate the response. I'll open a support ticket. Thanks again.
