RE: [Autoaccept-sink-devel] Problem with AutoAccept Sink

[Lundeen, D. C <DL1...@nc...>]

I noticed the same thing on my Exchange 2003 systems.  It appears to be
an issue with the locking mechanism in the AuotAccept program and with
the multi-threaded nature of Exchange event sinks (the real problem
could be that Exchange allows the sink to fire on the same message more
then once.)  In the OnSave routine a check is done to determine if a
sink is running on any messages in the current mailbox (makes sense
because you'd want to do them sequentially.)  Basically it uses a flag
that it writes into the message before it begins processing the message.
When the sink fires it checks for the existence of that flag in ANY of
the messages in the inbox, if one it found then it waits until that flag
is cleared indicating that, that message is done processing.  The
problem you seeing seems to occur when apparently the sink fires on a
message more then once, the second instance sits and waits until the
first on has completed, but when it resumes the original message has
been deleted, hence the error.

I believe you'll find that if you could check the mailbox where the
error occurred you'd find that one of the trace messages will indicate
that the request was processed correctly even though you received the
error.

I can send you my version of the OnSave routine if you like, but be
aware that I have changed a number of things in both the Sink dll and
the config program, so you might not be able to just cut and paste it in
before recompiling.

Hi,

I am using the AutoAccept Sink for some time with Exchange 2000 and I
noticed recently that there are many errors in the event log generated
by this product.

The events are all the same and they looks like this:

The description for Event ID ( 100 ) in Source ( AutoAccept Sink )
cannot be found. The local computer may not have the necessary registry
information or message DLL files to display messages from a remote
computer. The following information is part of the event:=20

Procedure Name  : OnSave

URL of Source Item:=20

-2147467259     Method '~' of object '~' failed

Can you please tell me why this is happen?

Except for this the product is working perfectly.

Thanks,

Moshe.
