Hi,

I am getting timeout exception from couchbase java sdk , Exception is as below:

Code where I am getting this exception is :

public String singleGetFromCouchBase(String key) {
String value = null;
StringDocument stringDocument = bucket.get(key, StringDocument.class);
if(stringDocument != null){
value = stringDocument.content();
}
return value;
}

Please help here I am unable to proceed further.

Thanks,
Bharat

Can you please share the client version, server version and a full set of Logs? Ideally DEBUG or TRACE.

Thanks!

Hi Daschl,

Thanks, we are using java-client-2.1.1 and our server version is : Version: 3.0.2-1603 Enterprise Edition (build-1603)

Please find the stack trace below:

Thank you! I was looking for the logs though, but I have an idea. Can you try

<dependencies>
    <dependency>
        <groupId>com.couchbase.client</groupId>
        <artifactId>java-client</artifactId>
        <version>2.1.2-dp</version>
    </dependency>
</dependencies>

<repositories>
    <repository>
        <id>couchbase</id>
        <name>couchbase repo</name>
        <url>http://files.couchbase.com/maven2</url>
        <snapshots><enabled>false</enabled></snapshots>
    </repository>
</repositories>

and see if it works? If so, 2.1.2 will be released soon. Alternatively you can try 2.1.0 since if that fixes it it was a regression introduced in 2.1.1.

Thank you Daschl, We have changed the version to 2.1.0 and error has been resolved.

Thanks,
Bharat

Hi…

I am getting almost exactly the same issue as described by OP.

I am using java-client-2.1.5 and server version 4.1.0-5005 Community Edition (build-5005).

Please advise.

Thanks!

@kscer timeouts are a very generic thing and heavily environment dependent. can you share some more information on your exact use case and stack trace with the issue?

Also, 2.1.5 is quite old by now, can you please upgrade to 2.3.6 and see if the issue persists? (2.1.x is not supported anymore, upgrading should be very painless)
