8916.0. "kernal memory fault panic" by NETRIX::"[email protected]" (Roberto Romani) Fri Feb 21 1997 00:43

Hello All,

	I received the following crash-data file from a customer,from the look of it
doesn't match 
anything I have seen in the v4.0 patch readme file.Has anybody seen this
before ?.
I could probably get the customer to put the following patches on just for
good measure but I would like
a second opinion

OSF400-111,112,114 for starters, but this look like a ACL problem to do with
nfs-flatten-mode 
(this may be a wild goose chase though..I should know better than speculate)

regards

    Roberto,
    
    please use CANASTA for the first step during crash analysis. See my
    reply regarding CANASTA in note #8897.3
    
    I've sent this case to CANASTA for you... There is NO OTHER PANIC with
    the SAME FOOTPRINT in the world-wide CANASTA case database and there is
    NO RULE describing the problem and/or the solution, so it's IPMT time !
    
    USEG is committed to CANASTA, so if they wouldn't provide CANASTA rules
    for known solutions, workarounds etc. they are the ones to handle the
    IPMT load...
    
    Volker.
