Hello, I’m using Couchbase 4.6.2 and JavaSDK 2.4.2 .My code works as scheduled job, every day with 5 minutes interval, but I got this error 1 or 2 times a day.
This is my connection code:
CouchbaseEnvironment env = DefaultCouchbaseEnvironment.builder().connectTimeout(20000L).build();
Cluster cluster = CouchbaseCluster.create(env, “10.10.10.149”);
I pass the cluster as parameter to other classes, and in that classes I open a different Bucket, upsert data, and close the Bucket. But this error happens sometimes and I can’t figure it out.
This is the error:
ERROR: Could not open bucket.
com.couchbase.client.core.config.ConfigurationException: Could not open bucket.

Is this error about connection issue or something caused by server?
