We have a AWS Neptune db.r4.large instance which with 2vCPUs can run 4 threads and hence 4 queries maximum at a time. We use the Gremlin Java client to connect to AWS Neptune. We are seeing regular persistent java.util.concurrent.TimeoutException exceptions while querying data.
Reading up on this AWS doc: https://docs.aws.amazon.com/neptune/latest/userguide/best-practices-gremlin-java-exceptions.html
It looks to be a case of client side throttling since we do not see any utilization of the Neptune queue with MainRequestQueuePendingRequests = 0. We did as recommended in the post (code below). With maxConnectionPoolSize = maxSimultaneousUsagePerConnection = maxInProcessPerConnection all set to 64, we have maxParallelQueries = 4096. Given our db instance and query latency, this seems like an overkill but we hoped we would at least shift some of these errors on to AWS Neptune to see the queue being utilized and see some throttling exceptions. However, all the requests that reach Neptune are processed correctly. The problem remains that almost half the requests never reach AWS Neptune and error out on the client side.
Other relevant metrics are the maxWaitForConnection = 16s (default) and the
avg(aws.neptune.gremlin_web_socket_open_connections) = ~10 (pretty steady). Anyone has any suggestions how we could resolve these exceptions?

I also came across this type of error, my solution was to change the jdk I was using and the exception disappeared! So I don't really know the root of the problem, but changing jdk works for me. You can try using the JDKs provided by intellij. This article can be of great help. https://www.jetbrains.com/help/idea/sdk.html#jdk
Like mentioned here we have almost the same issues with a java project (playframework) with neo4j-ogm and the ogm-bolt-driver (3.2.27). Connection resets sometimes, throws exception and reconnects with the next request (mostly).
The nodes will be queried from database via repositories and neo4j-ogm session (will be opened for small pieces of work).
Any advice will be appreciated.

As I mention in my answer here, this exception comes from Neo4j Java Driver and there may be several reasons for this to happen.
For instance, this might happen when driver acquires a connection from internal connection pool that has been idle for too long. Some cloud providers limit connection idle time for load balancers. Driver may fail as soon as it tries using such connection.
You can enable connection liveness check to assist with this. It makes sure that a short network exchange happens for every connection that has been idle over the configured timeout. If exchange fails, another connection is picked or established before it is provided for further driver usage. While this involves an extra network exchange, it is likely to prevent driver failures that might lead to higher-level retry management with potentially exponential delay. The timeout can be set to zero if you wish to test every connection.
Sample configuration:
var config = Config.builder()
.withConnectionLivenessCheckTimeout( 60000, TimeUnit.MILLISECONDS )
.build();
var driver = GraphDatabase.driver( URL, AuthTokens, config );
I am trying to load/write the data from Redis cache in my spark-sql java based application.
Here is my code:
SparkSession sprk = SparkSession.builder().appName("Bulk processing").master("local").config("spark.redis.host", "127.0.0.1")
.config("spark.redis.port", "57855").getOrCreate();
Dataset<Row> employeeDF = sprk.read().format("org.apache.spark.sql.redis").
option("table","employees").load();
employeeDF.show();

I use pre-packaged war file downloaded from Releases page.
Version 4.0.0
Interesting part is when I run microservice I don't get this error. It happens only with gateway.
Also when creating new gateway and run it exception also not appear. It happens after 1 day and after a day if you got this exception you get this every time...
I got the same error using the default configuration. The solution lies on the error message itself which is to increase the peer-node-read-timeout-ms value (default value is 200).
Go to your application.yml
server:
# see discussion about enable-self-preservation:
# https://github.com/jhipster/generator-jhipster/issues/3654
enable-self-preservation: false
peer-node-read-timeout-ms: 5000
We are having hard time figuring out the properties defined, minIdle, maxIdle etc.
we are seeing the following error with the following setting
InitialSize=5
maxActive=50
maxIdle=40
maxWait=2000

This is resolved. The issue was connection leak from the bad application code. The application code was written to access the underlying native connection to use Oracle Array Types and not managed properly. Changed the code to using SimpleNativeJdbcExtractor
