Last updated on MAY 11, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 10.2.0.1 to 10.2.0.4 [Release 10.2]
Information in this document applies to any platform.

Symptoms

Capture queue is spilling 100% of all the messages.

By generating the streams health check , we can see that the number of capture/propagation processes is different than the number of the subscribers from the sections
-capture/propagation processes
-Number of subscribers

Most probably you will find one or more extra subscribers with no corresponding propagation process.
