For a Veritas Cluster Server, the cluster may occasionally report error: V-16-2-13139 for a particular resource type.
Error: V-16-2-13139: Canceling thread (%s)
The agent prints this message with the thread ID of the thread that it is canceling.
Cancelation can occur at multiple times. The most common time for cancelation is when an agent function (entry point) times out.
Review the log for the corresponding agent and search around the same timestamp as logged in the error for the reasons that the thread was canceled.
