Description

At the moment I have no further idea how to get closer to the problem. That's why I'm asking here for more ideas.

I have described the problem on Zulip https://mariadb.zulipchat.com/#narrow/stream/118759-general/topic/Connector.2FJ.203.2E0.2E5.20-.20Got.20an.20error.20reading.20communication.20packe/near/304664479

Repeated:

After updating the JDBC driver from 2.7.5 to 3.0.5, I see a problem when updating a simple join table that I unfortunately cannot reproduce locally and on test stages.

The error code on the client side is SQLSTATE(08000), ErrorCode(1220)

Client side:

{{"org.hibernate.engine.jdbc.batch.internal.BatchingBatch","message":"HHH000315: Exception executing batch [java.sql.BatchUpdateException: java.sql.BatchUpdateException: java.sql.SQLNonTransientConnectionException: (conn=167) Socket error], SQL: insert into glaeubiger_gemeinde_bereich_relation (gemeinde_id, bereich_id) values (?, ?)","context":"default"
}}

root cause:

And today again a problem with the Maria JDBC Driver 3.0.8. Another app, another environment. So far I haven't been able to reproduce this error with a different environment either. The driver was released this year, but I'm surprised that there haven't been any problems with it so far.

There is one difference between 2.x and 3.x driver about batch : option `useBulkStmts` default now to true.
This means connector use a protocol dedicated for batch that is way faster than 2.7 implementation.

Could you indicate the server server ? There has been some issue with BULK commands a few years before, but all know issues are now resulved since some time if you are not using some old server version.

Comment by Torsten Liermann [ 2022-10-24 ]

@Diego Depin server versions: standalone 10.5.16 and docker image is 10.5.2

I don't think it's the server. If I start the app image in my local environment and connect to the original server, the usecase works.

Comment by Torsten Liermann [ 2022-10-29 ]

I updated the server versions. What feedback is still expected?

Comment by Torsten Liermann [ 2022-11-01 ]

With the parameter useBulkStmts=true in the jdbc url, the error does not occur with a Maria Database Server version 10.5.16.
The error cannot be provoked in a simulation of the problem using a test container (testcontainers.org) and a MariaDB Docker Image 10.5.16.

The error cannot be provoked with a unit test against the "faulty" database either. So the cause must be more complex than just the useBulkStmts=true parameter.

This is the unit test log output with useBulkStmts=true:

Comment by Diego Dupin [ 2022-11-03 ]

I've not been able to reproduce bug like this, and without further idea, i'm beeing stuck.
If you face this problem again, could you send server logs corresponding to the problem ?

Comment by Torsten Liermann [ 2022-11-05 ]

Here are the logs for useBulkStmt=false and useBulkStmt=true in case of an error. Repeating the other error case is not easily possible due to the complexity of the ops dependencies.

Can you have server logs at the same time of this error ?
