Hi,

We deployed titan1.1 for one of our project. Past three days no issues. From today, we got some issues TimeoutException from server side. After subsequent call we are getting same Exception.Every time we suppose to restart the server. Please suggest.

we used gremlin client to configure titanDB.

Configuration

-------------------

Cluster cluster = null;

//TODO get from configr

try {

String address = environment.getRequiredProperty(TITAN_SERVER);

int port = Integer.parseInt(environment.getRequiredProperty(TITAN_SERVER_PORT));

GryoMessageSerializerV1d0 serializerClass = null;

Cluster.Builder clusterBuilder = null;

Map<String, Object> configMap = null;

serializerClass = new GryoMessageSerializerV1d0();

configMap = new HashMap<String, Object>();

configMap.put("serializeResultToString", "true");

serializerClass.configure(configMap, null);

clusterBuilder = Cluster.build(address);

clusterBuilder.port(port);

clusterBuilder.serializer(serializerClass);

clusterBuilder.maxConnectionPoolSize(15);

clusterBuilder.maxWaitForConnection(500000);

cluster = clusterBuilder.create();

Client client = cluster.connect();

return client.init();

} catch(Exception ex) {

ex.printStackTrace();

System.exit(0);

}

Exception:
