I am getting Timeout exceptions even though there is not much load on the Couchbase server.

net.spy.memcached.OperationTimeoutException: Timeout waiting for value
        at net.spy.memcached.MemcachedClient.get(MemcachedClient.java:1003)
        at net.spy.memcached.MemcachedClient.get(MemcachedClient.java:1018)
        at com.eos.cache.CacheClient.get(CacheClient.java:280)
        at com.eos.cache.GenericCacheAccessObject.get(GenericCacheAccessObject.java:55)
...

This is how I am creating the client.

List<URI> uris = new ArrayList<URI>();
        String[] serverTokens = getServers().split(" ");
        for (int index = 0; index < serverTokens.length; index++) {
            uris.add(new URI(serverTokens[index]));
        }
        CouchbaseConnectionFactoryBuilder ccfb = new CouchbaseConnectionFactoryBuilder();
        ccfb.setProtocol(Protocol.BINARY);
        ccfb.setOpTimeout(10000); // wait up to 10 seconds for an operation to
        // succeed
        ccfb.setOpQueueMaxBlockTime(5000); // wait up to 5 seconds when trying
        // to enqueue an operation
        ccfb.setMaxReconnectDelay(1500);
        CouchbaseConnectionFactory cf = ccfb.buildCouchbaseConnection(uris, bucket, "");
        CouchbaseClient client = new CouchbaseClient(cf);

Please help me in resolving this issue. Let me know if further information is required.
