<P ALIGN=LEFT><FONT SIZE=2 FACE="Tahoma">Hello workflowers! The question that I put to you today is regarding the workings of the event queue.</FONT></P>
<P ALIGN=LEFT><FONT SIZE=2 FACE="Tahoma">We have seen in our Production environment that if the event queue has filled up and is not being cleared completely by every job run but in fact keeps on building up through time (as a result of a batch job that triggers many workflows), the event delivery job will deliver the most recent events instead of the oldest events. </FONT></P>
<P ALIGN=LEFT><FONT SIZE=2 FACE="Tahoma">In other words, the event queue is behaving as a LIFO (Last In First Out) queue instead of a FIFO (First In First Out) queue. It was my understanding that the queue should be FIFO.</FONT></P>
<P ALIGN=LEFT><FONT SIZE=2 FACE="Tahoma">Any comments? Anybody else seen this happening? Any solutions????</FONT></P>
<P ALIGN=LEFT><FONT SIZE=2 FACE="Tahoma">The sequencing is extremely important to some workflows that we have and we'd like to see the queue behave as a FIFO queue.</FONT></P>
