Intermittent Events not triggering from Event Queue

[Sue Doughty]

We're on ECC6.

We have workflows that are triggered when certain document types are
scanned into SAP.  The scanning of the image triggers the PREL ASSIGNED
event.  Up until recently there were no issues.  

In the last month or so, some of the events are not being triggered.  I
can see that the images were stored with the Employee in SAP, but no
event was triggered by the scanning.

I've been looking at the Event trace and can find no errors and no
evidence that the event was triggered for the images that were scanned
but no workflow was started.

There is no rhyme or reason for the missing workflows.  We'll go along
for a while and all will be fine and then I'll get emails that workflows
were not triggered on different dates.

Is there anywhere else I can look...tables, transactions, etc?  Could it
be with the way that the background job is set up that delivers the
events?  I have it running every six minutes.  We have all kinds of
events (hundreds of them) triggered during the day....could it be an
overload of events at one time?  Do events that are not delivered get
dropped if the background job is still delivering events when the next
job starts six minutes later?

Any help would be greatly appreciated.
