1278.0. "PCM v1.6-201 ACCVIO , PC=00026BA7" by KERNEL::ANDERSONS () Thu Apr 25 1996 07:02

Hello,

My customer has just installed ECO2 and is now having problems( or as he put it
'different errors' to the ones he had before). 
He has asked me to forward the ACCVIO to notes for the attention of Dan
Butterworth (Dan the customer is Phillip Baxter).

The problem is only with this Child Controller process which is one of six. The
accvio occurs every 24-48 hours. The customer is not willing to 'set debug' on
as this will use up to much disk space. 

I realize that you will need more info than the above but my knowledge of PCM is
very limited, this is what I have.......

VMS V6.1
PCM V1.6-201
VAX 4000-90

6 X Child process
LAT used for transport.

Just one more point, Phillip says the "CMHostControlErrorCD: code = -196" 
errors have only appeared since the upgrade to ECO2. He has installed the ECO2
patch to other systems and they are working fine.

Any help with this would be much appreciated.

Hello,

	We will check the code according to the register dump and send you our 
	conclusion.

    Re -2. In a nutshell, a data-structure has been stomped on. 
    R5 should have held a pointer to a structure and doesn't. The section of 
    code its in runs when the daemon has received a control message that says 
    an archive of a system has been completed. The pointer to the structure
    ( i.e., R5) came from another structure that was passed in as an
    argument. Since the failing instruction was the first use of R5 after
    the pointer was moved into it I'd say that the structure is corrupt.
    The real work is figuring out how.
    
    There is not enough stack context within the stack dump provided by the
    ACCVIO exception handler so we may need a process dump. The
    CONSOLE$STARTUP.COM will need to be modified so that it doesn't INSTALL
    the CONSOLE$DAEMON.EXE as a known image and PCM must then be fully
    restarted using CONSOLE$STARTUP. When the problem occurs, you'll
    get a CONSOLE$DAEMON.DMP in CONSOLE$TMP:. Make this file available
    for copying.
