Subject: Preemptive callback required

 I have just built William Lupton's pvload utility under 3.14.2 so that I
can call it from iocsh on a Linux box. I ran it with a test file and the
records got set correctly at startup however, I got the following message

dbServiceIO: preemptive callback required for direct memory interfacing
of CA channels to the DB.

 I looked at where the message was coming from but am not really any the
wiser as to what it is trying to tell me. Before I start looking at the
pvload code can someone explain what circumstances would trigger this
message.

  Regards

   Chris Mayer
