1218.0. "A1 fetcher seems to loop" by EVTAI1::PROT () Tue Aug 11 1992 10:02

    I have a problem with A1 fetcher on site with 350 users:
    
    The fetcher starts, process all the A1 mailbox pending messages, and
    then never finishes. If new messages come in A1 mailbox during its
    work,it doesn't process them, but is always running, doing a lot of IOs 
    and consuming CPU.
    
    The ALL-IN-1 function MAIL MTI_FETCH_REMOTE is working at this time .
    It seems to loop (SH PROC /CONT) but the loop is very large. The
    "current" message in A1 Mailbox is not processed. 
    
    If I stop it, the last "current" message in A1 mailbox is correctly
    processed. Then I'm sure the problem doesn't come from one NBS content.
    
    This problem appears in ALL-IN-1 2.4,after upgrading the ALL-IN-1
    DESKtop server from 1.0 to 1.1, but I can't for now, relate to
    something specificly in A1S.
    
    Any idea ?

    Contact your CSC - but check the number of records in 
    the fetcher queue - the record in pending file with a key
    "MAIL FETCHER"

    Not many, 5 now. (The firest and 4 continuation records) 
    But the mail count is 69 when I find 134 ".NBS" reference in the 5
    records.

    Are you certain that you have 134 nbs references in your FETCHER QUEUE
    (sorry I got the name wrong!) - You should only have one nbs file-
    sounds like a 'internal' record is bad.
    
    Someone (in Atlanta CSC)  should have a tool for digging out the bad one -
    a nasty and dirty alternaltive is to delete the entire FETCHER QUEUE.
    (WRITE DELETE CAB$PENDING KEY = "FETCHER QUEUE" ... might work)

1218.4Fetcher never stopsEVTAI1::PROTTue Aug 11 1992 12:1610
    I was doing $ MC MRMAN DU A1 to check the queue, and I saw that all the
    messages were fetched (one by one until 0). At this time the fetcher didn't
    stop run. ???
    
    Then new messages came in A1 mailbox, but from this moment, the fetcher
    works but doesn't fetch any new message until I will stop it and let a
    new OAMTIMAIL start.

    BTW -            
                     
   This problem is resolved... disk space on the A1 disk was exhausted, and
    the NBS files were created at 0 blocks until the space was cleared.
    This then left the fetcher looping on these corrupted files.
   
    Occured on V2.4 - fixes in place on V3.0 to prevent this happening -
    file creation error-checking, and disk space bounds checking.
   
    The ALL-IN-1 Desktop Server trace log was the culprit for filling
    diskspace.

    wrong - incorrect behaviour - once the fetcher had emptied N messages,
    and processed any retries, it should exit...
                                 
    Failure to exit was caused by NULL nbs files causinh infinite loop..
