Conference cookie::archive_backup

     Thomas,
    
     We have never seen this access violation before.  I have to discuss
     with more people here to see how we can debug this. If ABS gets
    accvio, it should get CMA exception from the CMA block we use. I did
    not think it was possible to die in the way it's reported in the log...
    
     Please post the save request show output for this request.
    
     I am assuming that you are using V2.1 ABS on V6.2 OpenVMS (alpha).
     What is the image id of the backup image you are using?  Do analy/image
     sys$system:backup.exe and report the image id in the header.
    
     I am assuing that you got the "failure to access storage class" error
    in the subsequent backup. The way to fix this problem is to 
    
    abs set storage XXXXX/novol
    
    and let ABS pick a new volume.  Due to the fatal error during backup,
    the volume is no longer useful.  However, ABS has mechanism to detect 
    this and remove the volume automatically from the strorage class.
    
    Before you issue "abs set storage XXXXX/novol" command, do the
    following and report us the result.
    
    Do show system and see if you see a process called  ABS$COORD_CLEAN  is
    out there.  Do abs show storage XXXXX/full and post the result.  Do
    storage show volume SLS015 and post the result.
    
    
    	That's it for now.  We'll keep looking.
    
    	Masami

    Masami,
    
    you're right it's OpenVMS Alpha V6.2, ABS V2.1.
    Backup image id: AXP V61R_62-000

    Because the tape wasn't allocated from anywhere, I aborted the jobs
    after a few hours (yesterday), set the storage-class to /NOVOL and restarted the
    jobs. For tonight the backups working fine again.

    Thomas,
    
    Since abs$coord_clean had access violation and died, it makes sense
    that the subsequent save was not able to allocate the tape. 
    abs$coord_clean automatically does set storage XXXX/novol for you 
    if the save aborted due to a fatal error (or if you stop/id the save
    process).  
    
    As for the access violation, both access violation took place within 
    a minute of time from each other.  Is there a possibility that some
    sort of system failure went through around that time?
    
    Also, the access violation from the save log is mysterious.  Since
    the code it is executing is within CMA try - endtry block (CMA
    exception handling), it should have been caught by CMA and get some
    CMA error along with the access violation informaiton.  I posted a
    note in CMA notes conference if this is at all possible.  I will confer
    with a local CMA expert also.

    Masami,
    
    the customer told me today, that just in the moment of the dump the pathworks
    license server also crashed with a register-dump. Could this be the
    reason of the problem?
    
      Thomas

    
    Thomas,
    
    I don't think that pathwork dump will affect us.  We do not have
    anything to do with pathwork process. However, it's getting more and
    more likely that something went wrong with the system at the moment and
    caused at least 3 processes to die.
