+<h4>CA Client Library's Search Datagram Interval Exponential Backoff
+Flawed</h4>
+
+<p>CA's search datagram interval exponential backoff should look like
+this:</p>
+
+<p>30mS, 60mS, 120mS, 240mS,...</p>
+
+<p>Or a similar behavior with higher initial delays resulting from a round
+trip time delay estimate greater than 30 mS. However, instead the backoff
+delays looked like this</p>
+
+<p>30 mS, 30mS, 30mS, 30mS, 30mS, 30mS, 60mS, 120mS, 240mS ...</p>
+
+<p>This also impacts what CA does when a channel disconnects or there is a
+beacon anomaly ( a new server event). The intent was to start the search
+delay for disconnected channels in these situations at 2 seconds but due to
+the above bug the delay was more like 64 mS. </p>
+
+<p>This bug appears only in earlier versions of EPICS R3.14</p>
