2452.0. "OAFC Buffer Overflow" by BAHTAT::BURTON (Jonathan Burton) Tue Mar 23 1993 11:50

I have a customer who gets the following error when trying to display all
connected clients using the MSC option:-

	Client buffer not big enough for requested information.

I have looked all over but have been unable to find out what needs to be
increased so that they can display the full list.This happens whenever there
are mor than 22  clients connected,before then the display is fine.

2452.1Known bugCHRLIE::HUSTONTue Mar 23 1993 14:247
    This is a known bug in the SM UI code that calls the FCS.
    
    What it means is that they made a call to the FCS, passed a buffer
    to put the return information in, and the buffer was not big
    enough.

2452.3%OAFC-W-BUFFOVFL Disconnect client problemsBUSHIE::SETHITue Sep 07 1993 02:5930
    A customer does the following:
    
    MFC MS MCS DC (Disconnect Client) and get the error message:
    
    %OAFC-W-BUFFOVFL, client buffer not big enough for requested
    information
    
    followed by:
    
    Server must be running to perform operation
    
    BUT the server is running.
    
    This happens on nodes in the cluster that have >100 users on a node
    with < 50 users, the customer does not get the above error message.  On
    my node with a couple of users I don't get the error message.
    
    The customer wants to know if there is a limit on the number of people
    using the server before you experience the problem ?  The main reason
    why they would like to know is because they are thinking of having
    multiple servers running so that they don't have to effect 100's of
    users if the server has to be shutdown.
    
    I think that I may have seen this problem reported somewhere but I just
    cannot find the topic.  Any pointers or help would be gratefully
    accepted.

2452.4Don't know the user countCHRLIE::HUSTONTue Sep 07 1993 15:2011
    
    This is the effect of a known bug. The MCS will make a call to the
    FCS to get info on the connected people. If there are over x people
    (sorry, don't know what x is), this error is returned. The bug is
    in the IOS UI code. It passes a buffer in, if the buffer is not 
    large enough for the info, this message is returned. What should
    now happen is the application (IOS UI) traps the error, makes the
    buffer bigger and tries again. It doesn't, hence the bug.

    Hi,
    
    This bug will be fixed in the next release (now in Field test) and was
    also fixed in MUPA.
    
    Cheers
