The fact that the record was processed, causes it to queue all the event
that the array changed. You are not really receiving all of them - you are
receiving copies of the most recent one. The array space required to queue
was deemed too much to copy the data into the queue. To ingest these at the
highest rate, some synchronization with the channel access client would be
worthwhile. An option:
make the image record scann Passive,
have the channel access client put a 1 to the PROC field to cause it to
process every time a new image is received.

It seems that it is a little unfair to send multiple copies of the same
array. Perhaps the default behavoir for arrays should be to cache the array.

Needless to say, it is a bad thing to take up more than 100% of the
processor.
