how does your client`s connection profile set?
have you add kvTimeout() to CouchbaseEnvironment.builder()?


Hi @gadipati,

we need more information to debug your issue.

Let’s start with:

  • How does your client/server setup look like?
  • How is your server cluster configured?
  • What timeout are you using and did you measure the latency on your network?
  • Do you see these timeouts in spikes or on a regular basis?
  • Can you share TRACE logs of your application?
