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

Posted on by GHogge

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'

following are two possible reasons, 2nd worked for me

-- Add the below permission to AOS SQL user

• db_ddladmin

• db_datareader

-- Update the below query

update SQLSystemVariables

set value = '4'

where parm = 'SYSTIMEZONESVERSION'
