Can I know what are potential causes of below exception? Why is heartbeat using in couchbase?
HB: Node 'http://xxxxxx:8091/pools' is not available.
System.Net.WebException: The request was aborted: The request was canceled.
at Couchbase.MessageStreamListener.Heartbeat.Worker(Object state)
Hi khwong9981 -
This is nothing to be alarmed about and is not related to the "Heartbleed" security exploit in Open SSL. The Couchbase client maintains a "heartbeat" with the cluster to ensure that the client state and the cluster can communicate.
It's not uncommon for this communication to be temporarily disrupted and for exceptions indicating that the communication has been disrupted to be logged. For example, when a process containing a client is terminated, you may see this exception in your logs.
Unless you cannot connect at all to your cluster or if your connected and operations are failing, everything is probably ok.
